About Me
Iam a gammer from the harsh uruguayan jungle (we dont even have a jungle down here, too cold, go and do some wikipedia of Uruguay). I used to do a podcast in spanish about videogames at Radio LevelUp but I dont do it anymore... anyway those guys are there still making it so you can give it a try if you understand spanish
And i can say "�aca �aca �aca" and i know how to pronoaunce it well since im a spanish speaker, so Im a superior race.
A couple of idiots may find funny that I dont have good english grammar, but again, they are probably idiots since they only speak/write one language...

Most of my time in the internet is because of games. I love videogames so much that i sleep with my girlfriend and my ds, at the same time... i call that a "threesome" and my humor doesnt get anything better than that.
Mostly im a PC gamer, i was going to buy a 360 but faulty crappy hardware told me not to since if it goes RRoD here I would have lost my money, and as a man Im entitled to the sweat of my brow. I want to fuck the Wii and I believe the PS3 is going to be the first console in space.

In the "real" life (come on, internet now is part of our lives anyway...), I study medicine (takes a lot of time and I cant spend enough of my time playing videogames). Is not what you would call a marriage made in heaven, if I wanted to game more I should have sutdy something related to pc�s, but I grown surrounded by computers and stuff so I chose the bio stuff instead. Anyway, little time to play video games if you dont want my biographical shit.

And the main reasson I play games for the story behind them. I love well written stories like Half Life series, of course Portal (kind of a Valve fan). Other great games include World Of Warcraft (not currently playing, actually I was never hardcore, but I enjoyed the experience a lot), and of course the classics like System Shock 2. Other great titles had stuck with me over the years, classics adventure games like Monkey Island, Indiana Jones and Grim Fandango.

So, best game experiences:
Half Life 2 (and the original Half Life of course).
System Shock 2
Grim Fandango
Indiana Jones and the Fate Of Atlantis
Monkey Island

Pharmacology for gamers: part 3
Velt | 8:35 PM on 04.06.2008 6 comments


Yes boys and girls, let’s try to get over my last post and get back to business (I got a lot of heat from my last post). I have been a bit busy, very busy actually, haven’t played anything in days… So I won’t go into something too complicated this time around. This is all about caffeine…
Yes, caffeine is a known substance, is like oil for people like me: it keeps us going. It keeps life easier and if you are a morning hater just like me then the more the better.

Let’s suppose that you don’t want to go with the heavy stuff like amphetamines (something I wrote about in the part 2 of this series). Is too complicated to get your hands on and you are sort of a pussy who just wants to drink something between matches in those FNF. You know, squeeze your brain for those great ATP molecules because you need to kill that bastard who is constantly spamming in your c-blog (always the same bastard… I know, don’t tell me about it you bastard, I know where you live).

You can find caffeine almost in everything nowadays. Let’s face it: tea, a coke, coffee, guarana (common in Brazil)… and in my country (Uruguay) people drinks something called “mate”, which has lots of caffeine.
But probably you don’t care about the costumes of a country which has 3.5 million people. I wouldn’t. I don’t drink mate, I stick to coffee because I love it. In the US energy drinks are more popular, I don’t know a lot about energy drink and I don’t get why you would drink it if you got a Starbucks (in Giant Bomb, they spend 15 minutes of a videogame podcast speaking about energy drinks… stupid).

But let’s try to explain what happens when you get yourself caffeine to your brain: it will increase the activity of dopamine neurotransmitter; also adrenaline (not cocks). This is kind of good because these substances will send your central pain threshold up, so it’s like an analgesic... not a very good one, but ok for the pain in your joints.

Very acute usage of caffeine increases the levels of serotonin that is involved in the mood (you know, serotonin reuptake inhibitors are drugs used in treating depression, so the more serotonin the better the general mood). This is cool, if you intoxicate with caffeine you won’t be a depressed idiot in the hospital wing… doctors hate intoxicated whining idiots… actually I hate whining idiots… ok, I hate idiots... and I know where you live!!

Back to caffeine.
Some drugs use caffeine as a vasodilator to increase the amount of oxygen and nutrient flow to the brain and muscles (like Theobromine). Other drugs will act as a positive ionotrope and chronotrope. A positive ionotrope is a substance that makes your heart pump better, a positive chronotrope will rise your ht (heart rate).
Let’s face it, an increased heart rate can cause some distal temblors (aka “I can’t keep my pulse steady”), which is not nice if you want precision with your fingers (mouse or controller). But maybe you prefer it over falling asleep and it does not happen in everyone anyway.

So yeah, you must know that this is a side effect of using too much caffeine (something close to 300mg a day can be too much). Some idiots inhalate crushed caffeine tablets (just like cocaine), so the effect is faster. The intoxication with caffeine is just like any other stimulant and I copy and past from other source: restlessness, nervousness, excitement, insomnia, flushing of the face, increased urination, gastrointestinal disturbance, muscle twitching, irritability, irregular or rapid heart beat, and psychomotor agitation. In cases of much larger overdoses mania, depression, lapses in judgment, disorientation, loss of social inhibition, delusions, hallucinations, psychosis and death may occur.
150 to 200 milligrams per kilogram, roughly 80 to 100 cups of coffee for an average adult taken within a limited time frame will kill you (heart failure). So there you go, suicide bot at your service.

Hope you enjoy this. I won’t include the disclaimer here because caffeine tablets are there for stupid idiots to abuse and I dont sell them. Rant about the dangers of caffeine would be like ranting about the dangers of video games.

I think I’ve grown a solid tolerance to caffeine. I can drink a 20 oz. bottle of Coke before bed and be just fine, though I don’t drink very much coffee (which I know is more potent) just because I don’t like the taste. Thanks for the biology lesson yet again.

Well the main advantage of energy drinks is that they are slightly more portable than a coffee machine and generally on sale at lans (where they don't want you spilling coffee everywhere). Plus sometimes you just wantsomething cold and iced coffee in cartons is pretty weak compared to making it yourself. Still nothing beats a cup of coffee in the morning... with maybe a little baileys.

Oh yeah protip; reduce your intake before exams so your chemical dependancy is reduced. That way when you start drinking it again immediately before you will get a much bigger effect off of a smaller amount and reduce the chance of overdosing

You know, I used to wonder what the fuck the side effect "Increased urination" was all about. Like you'd notice a difference in amount of pee, right? Then I was prescribed Vicodin for the first time. Good lord.
