Switching doctors might be best. I have ADHD (and bipolar and PTSD) and started having severe insomnia when I became perimenopausal. My doctor did not seem to realize how difficult it was for me to function on two or three hours sleep. I fired her and my new doc is much better. It took the new doc about six months to find the right combination but finally I sleep sufficient on *most* nights. Well mornings because I go to bed at 5am and sleep until noon.

Good luck to you in finding what helps you sleep. I know how frustrating that can be.
