Sleep Hygiene: Sorry to make you follow a link, but this gives you some great tips to try: http://sleepfoundation.org/ask-the-expert/sleep-hygiene This is probably all you need to do. You do seem to have hypothyroid based on the medicines you take, so getting your thyroid levels checked would also be helpful. An over the counter drug like melatonin or Benadryl (diphenhydramine) would be a distant next step after the above.
