There's something over the counter called unisom or doxylamine is the chemical name or whatever. My mom had been on ambien for years and years and eventually it quit working. I also have major sleep problems. I take 200mg of seroquel at night and it makes me very sleepy but still can't sleep. Somehow unisom works. My mom says is works better for her than ambien. It's like 12 dollars at walmart.
