My brain flits around all day long and it will not turn off at night to sleep. I wouldn't say so much racing thoughts but it just is thinking. The only thing that I have found that helps is Tizanidine (weird I know) but I can't take that more than 2 days in a row without having problems. The interesting things is that while my brain is going I have mild heart palpitations. Once the brain stops so do the palps. So I'm thinking if I stop the palpitations, maybe the brain would stop? I'm gonna talk to my doc next Friday but I'm curious if anyone has figure this out.
