My pdoc has increased my gabapentin during past episodes and once I've come down I've noticed the dose becomes too much for me and I get the same hungover feeling you're describing. I'm glad you're feeling better since you went down to 200mg.

Did you have a history of papasthesias prior to taking gabapentin?

I used to take it in very high doses (600/1200/1200mg) to treat dysthesias, but it stopped helping a long time ago. It's funny that I used to take so much of it with little or no effect before, but the difference between 300-400mg now can cause sedation, but then again, I'm on an altogether different drug cocktail now.

I hope that the parasthesias were random, and don't become a regular occurrence.
