After doing everything in my power for 7 years to avoid it, I have finally had to give in and start taking prednisone for my ulcerative colitis. I am here basically to whine about it, and I am only 3 weeks into it. So far I have had thrush, feel constantly like I have PMS and today I have headaches and sweats. I am really thankful that it has made an appreciable difference to my UC but really, it isn't a fun thing to take. Does your body eventually get used to it? I am only supposed to take it for a further 2 months or so hopefully.
