You can only do the best you can do. Healthy sleeping patterns, diet, exercise, therapy, medication, daily routine.... Etc.
At some point though we just have to accept this disorder is a part of who we are.
I am doing everything I can to stay stable, and it's a struggle. My brain wants to go totally batshit manic right now, and I have to do everything in my power to stay in control.

For me, the key is sleep. If I can't get at least 5-6 hours of sleep, I get in trouble. So far, I'm ok. I've only had a few nights without that much sleep, and got 6 hours last night.
If it's gets worse, I'll be forced to call my Pdoc, and get something to help me sleep, and unfortunately, since I'm manic, it will have to be a very, very strong drug!
