Suddenly I started having trouble falling asleep and if I woke up during the night, I couldn't get back to sleep. Melatonin didn't work for me either. My doctor prescribed 50 mg of Trazodone and it worked great. I didn't wake up feeling groggy. After taking it for a while I stopped taking it to see how I would sleep without it. I was back to sleeping through the night on my own. Guess my body and mind needed a little help for a while. Best of luck and I hope you start sleeping better soon!
