I have it. Honestly, I just overdose on sleeping medication. Not like Liza Minnelli overdose, but a little more than the recommended. I've tried about every kind too. Lunesta, Rozerem, Trazadone, plain Melatonin, and so far the best (and the cheapest) has been Tylenol Simply Sleep. Although sometimes if i really can't sleep then take the Simply Sleep and Melatonin. It literally has the effect of carbon monoxide.
