i'm taking 375 mg lyrica daily for persistent spasmodic leg pain, in addition to having received 3 spinal epidural injections over last 3 months. getting significant relief, 50-60%. i'm suffering from additional side effects, including occasional vision blurring, speech difficulty and confusion, but the rapid weight gain is what really concerns me. tried wellbutrin for about a monrh, didn't help at all, and had significant side effects of its own which for me made it intolerable. any advice?
