insomnia
"I bought melatonin 5mg. The first time I ever took it I didn't notice any difference. I still couldn't sleep and still woke up during the day. 6 months later, I decided to give it another try. I took one 5mg and it did nothing, so I decided to up my dose. The next night I took 10 mg about 30 to 40 minutes before sleeping. I kid you not I fell asleep so fast I didn't know what hit me. I slept without waking up for a complete 8 hours and didn't feel tired when I woke up. This has seriously helped me a lot. It had been years due to insomnia and scoliosis since I've had day much less months of good sleep. I highly recommend it. Play around with doses. Add 1/2 the dose or a whole pill of the dose you are already taking if it isn't working for you."
