How much were you taking and how quickly or slowly did you wean yourself off? I've been on 900 mg daily for five years (for sciatica and lower back pain) and while the gabapentin has reduced the pain considerably, I am concerned about taking it for the rest of my life. I also am not sure if it is blocking the pain, or if my sciatica has gone away on its own (which I know happens). I have read that stopping Gabapentin too quickly can result in severe withdrawal effects.
