Anyone on Lyrica for back problems?

Hi, my name is Cheri. I have been on Lyrica for almost a year now and find that weight loss is very slow compared to when I was not taking it. My weight goes up and down a lot instead of leveling off. Anyone else have this problem?? On Lyrica 150 3 times a day and will be on 200mg 3 times a day soon. Also take Cymbalta 60mg, Zanaflex 4mg (muscle relaxer), Adipex 37.5mg for apatite control,Sybicort, Rhinocort, and multivitamin. Dose anyone have any trouble losing weight on Lyrica? You can add me if you like.
