I put in a review on the product page, but I'll post it here too.
Chocomine does nothing for me. Zero. You all are wimps taking girly-man supplements.
*whiny voice* "PMS-ing? Here is a kleenex, my shoulder, and a serving of chocomine, you'll soon feel better." *whiny voice*
When you all come up with a real stimulant, let me know. Until then, sit there and let it bleed. I'll stick to my quad espressos and ephedrine.
Just kidding!

I didn't feel much. Doesn't taste good OR bad. Blah. Whatever, a waste of $11. Could be worse. If you are a lightweight, go for it. Otherwise, there are more effective things around...
