I used to drink about 12 cups of coffee a day strong. I mean like mud strong. I cycled creatine and put 10 lbs of water on in a weeks time. I drank water all day long while on my creatine cycle. I would wait a few hours in between creatine drinks before downing a pot of Java. When i wasn't cycling creatine i noticed a huge difference in my recovery, strength and sworeness. So i know the creatine was working. Its the best supp i've ever taken. For me, caffeine had no effect on the aborbstion. I had to stop drinking caffeine entirely now because i was always hot. heat would radiate out of my collar and my hands would sweat. It actually braught a case of hyperhydrosis on. I've been off caffeine for about 2 weeks now and man what a temperature change.
I wouldn't worry about 2 cups a day bro. Seriously! Thats nothing. How about a pot in one sitting? Then start worrying.
Scaggs.
