I go to the gym in the morning before work and usually by about lunchtime, I feel physically and mentally sluggish. I've backed away from caffeine for certain reasons and was wondering if there are any other things you know of that can help me stay awake. Unfortunately, not exercising in the morning and caffeine pills like No-Doz are not an option for me. And yes, I am getting plenty of sleep (~8 hours/day). I am thinking it may be caused by a deficiency in vitamins/minerals. Anybody have this problem? Any suggestions?
