It was hard to start, but exercise is the only thing that really gave me a long term solution. It was mentioned above, but I also agree with the diet remarks. I only drink coffee in the morning and not a lot. Caffeine, sugar and almost everything processed just spikes your blood sugar and causes a big lethargic crash. I stick to a schedule where I sleep at night and wake up by 7 am almost always. I try to never take naps and if so I set an alarm. It is too easy to sleep for a couple hours then be up late and repeat the whole cycle. Insomnia made me really depressed. I exercise first thing in the morning and eat breakfast. My bed is for sleeping, and I take melatonin. When it is hard to turn off my brain I use self guided meditation apps on my smart phone with ear buds. I have a friend with bipolar who stays up until 2am and sleeps until noon. She is having a very hard time controlling her symptoms and finding stability.
