The energy drinks have the opposite affect on me. My brother gave me one a couple weeks ago and I drank it over a 5 hr period while working on my truck-it was fine then.
I actually drank one yesterday at once, and man do I feel like shit. I don't even get a high from them, just a normal feeling then all at once it feels like I've ran a marathon. I am still feeling shitty from it today, which is what helped prompt me start this thread.
the gel I like is Accelerade gel I got a box of 24 of the vanilla and the chocolate when one of the local musclehead shops had a 2for1 dealio. made them cost about 50 cents each. at that price, not so bad. when I am really dead in the water a couple of them and a few slugs of water, I can get another hour or more of decent effort in.
