Thanks for all your responses. The reason I asked is because last night I slept all night and then took a five hour nap. I guess you can call it a nap. I get an overwhelming exhaustion feeling almost every day. Most nights I'm up all night in pain and don't sleep until that next night. It's a vicious cycle. Between the pain, fatigue and insomnia, I'm about to lose it. I tried Lyrics but the side affect I had was I couldn't walk straight. My balance was off and that scared me so I stopped taking it. Also, I stopped all meds for two days to see if they were causing the exhaustion and there was no change. Starting my meds again tomorrow. Going to see if my family doctor will give me B-12 shots again. It helps for a few days.

Hope everyone has a good night!
