yes, i was on prednisone for a year and I got off of it. I had to taper VERY slowly, like 1mg every other week or something crazy but eventually, i did get off of it. Take it slow. In the meantime, you should try rectal meds in addition to your current meds. I also bet humira has a copay assistance plan:
/www.humira.com/global/savings-and-co-pay50mg of 6mp is a low dose depending on your weight and how you metabolize it. You should get checked to see whether you're in the therapeutic range and increase the dose depending. Your symptoms don't sound too bad, maybe rectals could get you to 100% without doing anything too severe.
