Hi--I'm among the fortunate who have little pain from my idiopathic PN. Foot numbness, tingling, foot drop, and an awkward gait are the symptom that hit me suddenly about four years ago. My question: Has anyone else had no effect at all from Gabapentin or Duloxetine? I'm on the latter right now -- I was told it's an anti-depressant that helps with PN -- and I'm thinking about dropping it. I also take a nightly Ambien to sleep and I use a CPAP machine as well. My morning drowsiness sticks with me into the afternoon and I feel more disorganized than usual for a good part of the day. Any thought?
