Once went to my local Starbucks at 10 pm... one of those NEED MOCHA NOW moments. Was in bed by 11. I don't get how caffeine keeps people up. I've powered through 4 red bulls in 2 hours (I know... dumb) and gone to bed normally. I think my bloodstream is so saturated with caffeine that it has zero net effect on me. However, go a day without and I experience splitting headaches. Tea is for girls.</p> I’m with Rob on that one. Once went to my local Starbucks at 10 pm… one of those NEED MOCHA NOW moments.

I’ve decided though I’m going to start dirnking mroe tea again.

I'm definitely a fast caffeine metabolizer. I'm guessing it only has a half life of about 30 minutes in me. Do I have Fran beat? 30 minutes post-fix I often feel the urge to sleep, and have never connected caffeine to sleeplessness. The engineer in me also wants to speculate that the cycle would reach steady state after a day or two of consistent caffeine fixes, but I'm too lazy to prove it. I'm also guessing that as time goes on there is a departure from the half-life decay curve. I think a lot of my wife's headaches can be connected to inadvertent caffeine withdrawl. Anyway good post...</p> Interesting. I’m definitely a fast caffeine metabolizer. I’m guessing it only has a half life of about 30 minutes in me.
