No clue on pills but eating healthy and exercise is a great way to get more energy while getting in better shape. You might be a little bit sore at the start but if you get into a rhythm and keep at it you will have a ton more energy and that fatigue won't be a big deal.
That's assuming that the fatigue is not caused by some sort of medical condition.
Oh yeah I work out after work but everyone tells me do it first thing in the morning (5 a.m.) gives you more energy throughout the day. But have yet to make the transition.
