I have heard bad things about using benedryl for sleep. I have severe osteoporosis and I follow that list and recently learned that melatonin is effective in treating bone loss. It actually stimulates bone growth. I was skeptical of its sleep inducing benefits as I had tried it years ago for that. The first night I took it an hour before bedtime and I fell asleep and did not wake up all night. I am going to keep using it for the osteoporosis and although I don't always need help sleeping I usually cannot sleep through the night. I would encourage anyone to try melatonin for sleep in place of benedryl.
