I have chronic pain and have trouble sleeping it takes a little while to fall asleep but i wake up 5-6 times a night and toss and turn and have a very hard time getting back to bed the slightest noise seems to wake me up and i even wear earplugs. Im wondering whats the best sleeping pill for longer term use with little to no side effects/rebound insomnia. I currently take Zopiclone but i know its only a shortterm pill. Any suggestions would be great.
