The days i have to go to work i have to wake up at 5am. I wont drink coffee in the morning b/c i work in E.R. and it's pretty crazy there anyway, you don't need it. But before i leave i take a cup of coffee w/ me and sip on the way home so i can have some energy before hitting the weights. If not i'll fall asleep in the gym and pick up the little weights. It helps me a lot just don't use it so frequently that you get used to it and its effects diminish.
