Ryan,
I've tried the 5 HtP, it didn't seem to do much for me. I didn't sleep better or feel more calm. I was taking it as recommended 300 mgs at bedtime. maybe a practitioner might be able to adjust the dosage.
for sleep, I had better results with L tryptophan. you can get it from a compound chemist. I'm not sure if a prescription is needed. my doctor recommended up to one gram at bedtime. seems I did sleep a bit more and better quality.
Love from Lenina
