hi all, did anyone suffer with heartburn or indigestion whilst following their pre-op diet. As my bmi is fairly low i was told that if i didnt want to do the milk diet i could follow 1000 calories per day, but decided to do slimfasts as this takes the temptation away from eating, and even though i like the slimfasts i am really suffering from heartburn. I have used slimfasts before and they have never affected me like this. Would be grateful for any advice xx:sigh:
