Hey,Firstly, do food intolerances develop over night? Last week I ate alot of soya one day which caused my IBS to flare up. After giving my stomach a rest for a week I had a decaf-cuppa tea with soya milk and it caused me to be bloated and have stomach pains. I'm already intolerant to wheat, gluten and lactose!Secondly, is IBS temporary or is this a condition I will have to live with for the rest of my life? Will it go as it started - overnight? (one can only hope).Thanks,Sophie.
