So you don't exercise ? How about swimming ? Should also help you with the sleep, from the exhaustion. Like try swimming for 1 hour uninterrupted and you'll be ripped/slept.
I don't swimming. I just walk to the office or store. That's my daily exercise. Anyway, thank you for recommending swimming to me. I want to give it a try.
I'm on my first week of swimming and am really liking it (used to kickbox + run previously). Hell you can even get water-resistant mp3-player (i did). But just walking is too little.
