I was on neurontin for awhile and where i did not gain in pounds it made me bloat like crazy but i maintained 250 lbs. now why i mean by bloat. I went from a size 38 waist to a size 44 in a week. now when I stopped taking it i went right back down to 38in.waist. actually went down to 36. but when I started lyrics. wow. I am a size 42 now and I just weighed in at 325. I've only been on lyrica for 6 months. I believe these are different for each person. why not as we are all different so our reactions will be as well. good luck
