What medicine will help me sleep out of duloxytene, trazodone, gabapentin, or naproxen?

I started taking trazodone about 6 yrs ago after the doctors stopped prescribing ativan to me. I started at 50mg and worked up to one 100mg tablet at bedtime. It definitely helps me with sleeping. The only side affect I experience is dry mouth.
I've also taken duloxetine and gabapentin in the past for pain but neither of these were any help with sleeping.

Traz. Should def help you sleep, but sweetie. None of those meds you have listed are technically pain medications.
I get it, all together they may help you with some pain relief but. Of course you haven't said what your issue is. To me, that's just an odd combo of medication to take when one med could do the trick completely. For PAIN. (Yes, I realize, in combination the listed drugs could help with varying levels and types of pain.)
Good Luck & good night.

Hi, Bambilee!
That would be your trazodone. One of it's very common side effects is drowsiness and it affects over 40% of users.
