What's the best way to give my digestive system a rest?

I have IBS. I’ve gone a little mad on food in the past few days – emotional issues. But I’m wanting to get back on track with not overeating and give my digestive system a rest. I normally do weight watchers and I’m not really sure that even that kind of a diet is very restful for one’s digestion…all the sugar in the low fat products is quite high.

Obviously my first thought is eating just fruit and veg or even fasting…but I don’t really want to fast as I think my system might just shut down completely. What about eating fish? Cutting out meat? Starch? Would like your thoughts on calming and resting my digestive system and giving it some TLC. Probably need time-scale indications as well where necessary. Thank you

It’s sure needs it…. :-(
