I was on Lyrica for Fibro and had to stop taking it due to the horrible side effects. I gained about 30 lbs in 13 weeks on Lyrica. It does not matter what you eat or don't eat, the weight gain is due to fluid retention.
Now that I have stopped Lyrica, I am on Cymbalta which does not seem to be as effective for the pain as Lyrica, but no weight gain yet. I am suffering horrible migraine headaches which I did not have one headache on Lyrica. My doctor has since prescribed Tramadol for the breakthrough pain and headaches, but it is not very good at all.
I guess my search for the right combo of medications will go on for a while.
