In a previous post it said 15mgs. prednisone was low enough not to cause side effects. A 2 year treatment started at 30mgs and tapered to 7.5 mgs. Was ravenously hungry the entire time. Would have gained mega lbs except for absolute self control. Slept very little and went like hell while awake. I was me to the 10th power and then some. My bones took a big hit and now have the dreaded osteoporosis. Be careful with this stuff because it can do bad things to you even in low doses. We are all different.
