The only OTC sleep aid that has helped me was Aluna but my body adjusted to it quickly. On test cycles my sleep is terrible. I've tried OTC aids, Ambien - that only let me sleep for a couple of hours, Xanax but I could see myself geting to like those too much. 1 10mg Valium does the trick for me. I fall asleep quickly and sleep a good 7 hours and wake up without any kind of lethargic feeling. When the cycles over, I don't need the V's anymore and can put them away until the next time.
