dudes, i broke down and decided to give this supplement a try and...OH MY GOD! it was so hot out yesterday that i experienced everything from the sweats to the jitters using this supp. then, i got real hungry, and last night i was up until almost 2:30! i followed directions perfectly, to the t, and i didn't over indulge in caffeine. what is up with this supplement?! i took it at roughly 8 a.m. in the morning, and i couldn't fall asleep last night! today, i only took 3 instead of 4. anybody else experience any side effects with this stuff?!
