You should still try the over-the-counter doxylamine succinate (25 mg), a sleep aid that is inexpensive, sold at Costco as "Sleep Aid" for like $7 for a two bottle package. It was formerly sold as Unisom, which is more commonly sold now with the ingredient being diphenhydramine (Benadryl). There is a version of Unison which is the doxylamine succinate, but you need to read all the Unison labels carefully to see which it is. Start with a half tablet, because it is pretty effective, will cause you perhaps to be groggy after you wake in the AM if you take an entire tablet (at first). It's an antihistamine with the side effect of drowsiness.
