Let me tell you. I got prescribed Prednisone for my asthma and the side effects have been as pronounced (if not more so) as the intended effect.
Difficult to get to/stay asleep and yet Im wide awake and fully energized all day.
Im in a great/peppy mood UNTIL something happens that is (subjectively) mildly inconvenient or upsetting, at which point Im ready to pop someone or throw something.
One thing that has surprised me is my lack of a gain in appetite. I'd say if anything I've been less hungry than usual (although that may be because I've been noticeably more picky at my appearance, which in itself makes me not want to eat).
Enthusiasm at the gym has been 10/10 too so that's nice.
