I think I have insomnia. I haven't had a good nights sleep in so long and I always wake with back pain or something. I usually sleep for a couple of hours, four at most if I'm exhausted. I don't like taking any kind of medicine if I don't have to but I've been getting more shifts at work so I decided to buck up and take some sleeping pills. This is the third night I've taken them and I still haven't slept. I don't know what to do.
