Since starting gnereic levo four months ago, I have had a tremendous amount of reactions. I did not think nothing of it the first two months because I thought it was part of the process. Anyway within a half hour of taking it I would feel like my head was in a cloud, disoriented, spaced out, and tiered. It was bringing my levels down and I was only on 25mcg. As time went on and I tried to increase even a minimal amount I would get blurred vision, dizzyness, more spaced out, and developed itching so severe in throat and ears I wanted to die. Went off the meds for four days and everything started to clear. I also had anxiety which I developed and I am by no means hyper not by numbers anyway.. Has generic levo done this to anyone else. Also a pressure in my head and my eyes feel like all the muscles surrounding them are going to pop. Started a new levo called Tirosint which only has levo water and glycerine in it.. I had blurred vision before but every increase seems to make it worse.
