I was more or less hooked on ambien for a long time. My pdoc put me on 50mg of trazodone. It didn't help. He upped it to 100mg. I take it 30minutes before I intend to try to fall asleep. For those thirty minutes I relax. No tv (usually) no computer, no audiobooks, no podcasts, not music, no "to do" list conversations with my wife. In fact, no even mildly stressful conversations. I do my Alexander Technique lying down for 15 minutes. Then I'll read or write for ten to fifteen minutes. Then I close my eyes and fall asleep within a few minutes. I sleep for at least seven hours, maybe waking once to yes the bathroom, but then I'm right back asleep.
I've found traz to be very effective when on the right dosage, in conjunction with my no stimulation for a half hour policy. But it did take about a week to really get it down. I've been on it for about a month. Ask your doctor about increasing the dose.
