ngwen,
Prednisone makes ppl. starving
....the most of us eating much more than usual.
I have these bubbles and sounds in my tummy. The tummy is talking to you telling you that it's not having a good time ;-) Could be a part of a flare.
Try to use probiotics. Buy some good ones, and buy yoghurt containing probiotic bacterias like lactobacillus acidophilus, lact. bulgaricus and so on. Try to find sugar reduced yoghurt or yoghurt drinks / cultura drinks with those bacterias.
Have a nice day
From Ingrid
