UPDATE 3/26/18: Last neurologist visit on 3/21 has me on an agreed upon path of getting off the Neupro patch and all dopamine agonists. Currently still on the Neupro 3mg and now taking Gabapentin 300mg 4 times per day. Instructed to reduce Neupro to 2mg on 4/6/18, then switch to Gabapentin 400mg 3 times per day.
So far the Gapapentin has greatly reduced, almost eliminating, my day time muscle contracting/jerking and I'm actually able to sit for a prolonged time. I hope this continues!
My next visit is 4/11/18 and really don't know what the plan is after that.
I also learned that taking magnesium may decrease the effectiveness of the gabapentin, so I will cease the magnesium.
Thank you for all your helpful comments and for this site which has educated me like no other!
