I take 300 mgs of a Lyrica a day...I have had weight gain, and it is a listed side effect. What dose are you on? Maybe they need to cut you back a little and still get the relief you need, or give you the same amount only 2 times a day, instead of 3 as most are prescribed.
Hope this helps.

Tried Lyrica for sciatica. Ended up with a significant weight gain without any pain relief. I mostly just remember being ravenously hungry, 24/7. Actual hunger pains, like I hadn't eaten in days.

I've not had a positive experience on it but others have success.
