I need to work 18 hours everyday for the next couple months. Is there anything you guys could suggest to keep me awake and alert...preferably OTC, but if I can get it quick then I'm ok with that to. Diet wise I'm relying on a lt of shakes, and 3 lean protein, complex carb meals. Training will be once a week, basically a push, pull, and leg movement and then out. My job is fairly physical so I don't see me doing much more than that.
