only if it has an effect on you, I tried it many times and the only effect it seems to have on me is the bitter taste and heart palpitations if I drink too much of it.

if I'm tired or sleepy and drink it, I'm still tired/sleepy but with a higher blood pressure/heart rate.

sometimes I wonder if it's just people that oversell the effect of coffee.

You might be like me and apparently 1/5th of the human population doesn't really feel the effects of caffeine. Basically goes in and out of your system without 'proper processing'. Been years since I read about it, so things might have become more clear.

I can drink coffee/red bull all day and it'll do very little. Can drink just before going to bed and sleep just fine.

I'll try to find the study on this again if you're interested.

Some coffees with high caffeine have this effect on me as well. I find that different brands of coffees have very different effects on me, I can even get a good coffee feeling from some decafs. I'm convinced it's the other alkaloids in there besides caffeine that I like
