anybody use anything to keep them going throughout the day? i don't mean pre-workout i'm looking for something that lasts longer, preferribly without crashing. i'm going to be starting school on monday full-time and also be working full-time so i'm going to be running on 5 hours of sleep for the next year.:(
i think xenadrine makes an 8 hour energy supp. anybody try this before?
