AmyBeth:
I use Gabapentin and I always take before bed. I use it for nuropathy associated with type 1 diabetes. In my experience people either find it works well or not at all. I suggest it for all people who I know that have T1d never pain. Some love it, some claim it is not worth a darn and move on. There seems to be little way to tell without trying it.
I wish you well and of course your doctor will be the best given your symptoms and the profile of the medication.
