I am 39 and work out 4-5 times a week, an hour to hour and half. I get plenty of rest each night, eat a breakfast and lunch full of protein and plenty of water during my workouts. The problem is I get extremely sleepy an hour after my workouts. To the point where I want to start drinking Red Bull so I can stay awake! What could be wrong??


my gut reaction is it could be that you're just tired because you've just expended so many calories.
