Need help to Fight cravings & IC

A married mom of 3, running all the time. I am looking for some support from others like me that battle the craving for sweets. I think I get a handle on it, and then I screw up; no better than a drug addict at times. As if that isn't enough, I have interstial Cystitis which severly limits my food options, not to mention trying to exercise without causing severe bladder pain. I would really like to talk with others that have these issues as well, and see what works for you, if anything, looking for ideas. Thank you.
