Hey Cate, it has been so long since I posted on your diary that I cannot begin to catch up. And you are so good about posting to mine, makes me feel a bit bad.
I agree with LaMa, listen to your doctor. I do not fast, but have in the past, I once went a full week. The huge binge that ended it made up for all the good the fast did me. I know others are doing well with IF, and that you have had some success with it as well. I have considered it, Flyer has made me a believer, but for me what I am doing is working so I have not tried. I am sure you will work out what's best for you.
