It's hard when I feel this way because honestly when I'm at where you're at in the past I can put all sorts of strategies in place, and they don't necessarily work for me.
But one of the key things I know is this: Routine.
First and foremost - try and keep as regular a sleep routine as possible.
And then checking what the rest of your regular routine is doing.
If I'm exercising to much I'm probably on the high end of hypo spectrum, this is an indicator that I may need to slow down physically exerting myself.
Eating - remembering to eat (whenever it is that you usually eat) - because your body needs fuel
Drinking 8 glasses of water a day
Watching how much time I spend - am I over doing - say facebook, PC

, ... whatever
About finding that "somewhere in the middle" balance.
