I've got a sleep problem, I always wake up at night
Scott_MacGregor: When you work out your burning energy (calories) and losing water through sweat.  1. Try eating an extra healthy snack like a cup of yogurt and a piece of fruit before you go to bed every day, like a ritual even if you’re not hungry.


  2. Your body seems to need more water to replenish what you sweat out, that’s why you’re thirsty. Try hydrating yourself more by drinking "a lot" of water starting when you get up in the morning and sipping all day long like bodybuilders do.

Maybe that will help.
