I only go hypo manic so I still have some control over things.
I try to work from home rather than going out of the house. If I have to go to work then it's no stops on the way. I try to find boring work to do rather than really stimulating work. I also have to limit my time in front of the computer and take lots of breaks....
I take sleeping pills to make sure I get some sleep... and antipsychotics... even if I can't sleep I don't let myself get out of bed, I listen to relaxing music instead.
I understand this won't work for everyone but maybe it could help someone...
Basically my rule is if I'm high and want to go out, I have to stay in, if I'm low and want to stay in, I have to go out!!!!
