I tried a mix of Unisom (doxylamine) and melatonin that night and I managed to fall asleep, although it took a good while and didnt think it was gonna happen at first.

I've had mixed results with melatonin before and DPH based sleep aids (benadryl, Zquil) tend to make me drowsy as hell for a few hours without falling asleep If something like that happens again though, I'll probably see a doctor.
