Donna,
I've been on Zanaflex for over 3 yrs. and it's really helped me considerably. I take 2mg. twice a day then 8 mg. at bedtime. It would put me out when I first started taking it but my dr. increased the dosage slowly and now it doesn't bother me at all- but of course, I wouldn't take the full 8mg. dose during the day. Just make sure you check with your dr. before you change your dosage. I haven't tried Cymbalta although my neuro wrote a prescription for it last year. I never filled it because it wasn't covered by our insurance plus I'd read that it caused weight gain too and I'd already gained PLENTY thanks to the Neurontin.
