I have been taking the melatonin, the sleep doctor said that I should take a low dosage several hours before I go to sleep. I can maintain my sleep for a while, but it will go back after a while. A study showed that 90% of people with the sleep disorder relapse to their old sleeping pattern within a year

If too high of a dosage of the melatonin is used, I don't think the brain will produce its own melatonin normally. I wish I could just get a stronger sedative, but I don't think they'll prescribe one, since I'm young and have a very low body mass index.
