ibromyalgia
"Have been taking Methadone, Zanaflex and Mobic for quite a while for both Fibromyalgia and Rheumatoid Arthritis.  Tried Neurotin but it knocked me flat, finally switched to Lyrica, but I am so medicine sensitive that can only take 25mg in a.m. and 50 mg. at night. It is helping, however I become groggy and have gained 20 lbs. The weight gain doesn't help the Fibromyalgia, but the pain is unbearable so will take it."
