Hello. I have bipolar disorder. For the last week, I felt increased enjoyment from everything. Video games, reading, going on long walks with my dog, I was more outgoing, social, funny, etc. The thing is I ve been sleeping more. Like 10-12 hours a night, but feeling great and full of energy. I don t need coffee. That feeling has ended and I have less interest in things I used to enjoy more, less social, etc. But my sleeping went back to 8 hours a night. I don t understand it if manic episodes are supposed to make you sleep less. I have been taking the same medications for the past 4 months, nothing has changed.
