Well,when I get occasional sleep problems (falling asleep)
I use an over the counter product I HIGHLY recommend.
It is called ALLUNA(made by the makers of sominex I beleive)
This is a completely herbal pill (you're supposed to take 2 but one works for me)that just lets you fall asleep naturally.
It says right on the package it is NOT a drug but a dietary supplement.
Some people notice it working after a few days ..as I said with me it works in one night.
So I would try that.It is a combination of Valerian and Hops I believe.
Good luck.
