Thank you @jakedduck1 - I have been doing some research, so while I strongly suspect it's the Gabapentin I do realize this could be serious. My web searches have been exhausting as they basically all say the same thing - but the potential of epilepsy is one that I took off the list thinking the Gabapentin would have reduced that symptom. Is that a wrong assumption? And apparently some types of migraines have this as a symptom - who knew?!?

I try not to get TOO freaked out by the info Dr. Google makes available to me, but will definitely bring this to my doctor's attention when I see him on January 17th. Even if it didn't have the potential to be serious - it is CRAZY-MAKING! In the meantime I have decided to keep a jar of Tiger Balm nearby so I can sniff it at will, and have started to decrease the amount of Gabapentin I'm taking (last night I reduced from 500 mg to 400 mg) to see if that makes a difference. God knows the increase in Gabapentin has done nothing to reduce my pain, so that really sucks too 🙁
