green tea, coffee, redline energy drink, xs energy dink, plus take a multi vitamin w/green tea extract in it..
those are pretty much all i ever take, i just rotate every few weeks...
i never drink a whole redline/xs/or coffee at once, i just can't handle it. i feel too wired and i get sick. Wierd thing is i can pound green tea all day and it gets me wired but not sick..
