I've been on prednisone for 15 months now and have been around 10 mg most of the time, but have been up to 30 and down to 5. I haven't gained weight or developed moon face but am having a lot of problems with blurry vision (will be seeing an eye dr again tomorrow). We've tapered me down 5 mg at a time when I was on 30, but now we do it 1 mg at a time, as I can tell a difference just going down that amount.
Crohn's Disease, Acid Reflux/Gastritis, Hashimoto's Thyroiditis, Endometriosis, Arthritis, Depression/Anxiety. Too many meds to list them all. =)
