I have been on Levoxyl since I was 19. I am now 49 and a yr ago because of cronic fatigue I took myself off. I noticed I was awake again, my back, legs and teeth quit hurting, I went back on it because the blood test came back funky and after just 2 weeks back on it I feel awful. My back and body hurt so severely I cant stand it and Im taking vicodin I had laying around the house. Tonight its almost unbeable and is interfering with my job. There has got to be an alternative to this type of pain..
