Didn't read all other replies, but as someone who's been taking lyrica on and off for about 9 months, I have had no problems discontinuing and using on an as needed basis. However, the most I've been on is 150mg/day. Anything higher and I can't walk straight and feel drunk.
I can't decide if it is worthwhile. For a long stretch of time I felt better, then the burning came back, so I stopped it ,figuring it wasn't helping. Got worse,so started it again..helped a little, got scared of the side effects, etc etc I am inconsistent and also just don't want to be drugged up. I understand that fear.
I am also on oxycodone, and that is very addictive in comparison. I take a benzo up to 4x a week, at a small dose and that calms everything down. But I can tell when its out of my system because I'm an anxious painful wreck. The stress of anxiety seems to elevate the pain.

I suggest weaning if you're sure you are ready, and keeping some on hand if you find it is too painful .

Best of luck
