I have tons of anxiety at night and have for years. Even with meds i still have problems - one thing my pdoc told me to do which has been helping is to write in a journal before I go to sleep about whatever is making me anxious - I had something specific at the time - now I write about anything i think I might get panicky about - and I also write how i want to put all the stress in the journal...it has definitely been helping - I wake up way less at night.
