I have been tapering since May when I started on azathioprine (Imuran) First it was 60/50 and then a few weeks later 60/40 I felt alright...I went down to 60/20 where I stayed for a few months then just recently in Oct I started the taper again. Once I hit the 0 days I have started feeling like poop...It got worse when in late November I started the 50/0...Called my neuro and he wants me to stay at 50/0 till I see him in February. Thing is starting to get sick to my stomach on the 0 days. The 50 days aren't so strong anymore. This past week my breathing feels weird. not like i am getting enough Oxygen, but then I can take a deep breath fine. I wish he would of kept me on at least 10mg and tried to taper the other. Because this is not working, he doesn't think prednisone is doing anything but I can say it has. I can talk on my prednisone days where i struggle on my 0 days. I am at a hard spot because this is just making me feel like a walking zombie..
