Weight Gain and Lyrica - I Need Advice

I need some advice and personal experiences/opinions here. My insurance does not cover Lyrica, but my doctor said she'd try to convince someone else in the system to cover it for me so that I can try it for my Fibro.

The problem is this, though. I hear Lyrica causes weight gain. How much weight gain does it cause?? I am a recovering/recovered anorexic, and while I have two and a half years of recovery behind me, I know that I cannot handle gaining more weight than I already have put on. I think that gaining a lot of weight due to a medication to help me with my pain would only cause me to go back sliding into my eating disorder, and that would kind of defeat the purpose of the med helping me.

So, I wanted to know if Lyrica has made you gain weight, and if so, about how much? If you would rather, you can PM me answers. I won't share the info with anyone about weight if you decide to PM.

Thanks in adavnce!
