I've been on Lyrica for 2 years now for nephropathy and shingles pain. At first I was taking 100mg x3 a day (along with some other medicines) and I was like a zombie. I am no longer taking the other medicines and just cut back my Lyrica to 50mg x2 because I have gained over 40 pounds!! I am no longer a zombie but the pain is coming back. I am 5'2" and look like i'm 12 months pregnant at 170 lbs!!! I have a very low pain threshold and now I have restless leg syndrome in addition to the nephropathy. I tried pregabalin and that did not work! With Lyrica... no pain... but I keep gaining weight... HELP!
