I still have much difficulty getting to sleep and sleeping. However, the sleep I do get is better quality ever since I stopped taking those meds. Especially Seroquel i think that stuff is dangerous.
Oh yea, if you stop taking sleep meds, prepare for a few weeks of night terrors or nightmares. But if you do get past it it will be great.

Oh and you probably have to consult with your doc before trying this.
I didn't and had a few rough months since I quit benzos cold turkey and after the fact learned I could have died. It was a miserable experience.

Good luck with whatever you do.
Lavendar, valerian tea, warm milk, 5 htp, eat whole grains lots of veggies.
