How much caffeine is TOO much?

Question

I plan on going on a gaming marathon before the end of summer.

How much caffeiene would be too much? I plan on consuming sugar-free bawls (most of the energy comes from that Guarana berry.)

Answer 1

If the cat sneezing makes you jump, you've had too much caffeine.  If you freak because you spilled a little bit of coffee, you've had too much caffeine.  If you feel like cleaning your house from top to bottom and then starting all over again, you've had too much caffeine.  If you blow off a meal for more coffee, you've had too much caffeine.  If you are still on Yahoo Answers at 4 a.m., you've had WAY too much caffeine!!!

Seriously though, I generally have 2 cups every morning.  If I have three, I begin to feel that any of the above can apply to me.  However, tonight I had two more, and I think I'll be on Yahoo Answers for a while.

Answer 2

It is illegal to serve anything that contains more than 525 MG of caffine, best answer, goto starbucks and get a drink with 6 shots.
