I've had my suspicions I'm intolerant to eithe rlactose or dairy. For a start when I was born 4 weeks early I was being sick all the time and had really bad colic, the Dr's said I was intolerant to milk and I was then put on soya (they never did any tests, that's just what my Mum was told to do).I've been plagued with stomach pains and nausea for as long as I can remember but my Dr just puts it down to IBS. I did a 5 week exclusion diet and cut out completely wheat and gluten (very strict) but I felt no better at all. So my next thing was dairy. I told my Dr and she said be careful as you can end up living on lettuce leaves (I managed). For the first 2 weeks no pain at all (still had the nausea but that could be my anxiety) then suddenly it came back out of nowhere. I think it's because I had slightly relaxed and started having milk in my 2 cups of tea a day (and I ate the occasional lump of chocolate). This diet ended in December as I wanted to enjoy the foods of Xmas.Started a healthy eating plan 3 or so weeks ago and cut out chocolate totally and cereal as I knew it affected me. Last night I had one funsize bar of chocolate as treat for the weekend (don't drink, don't have takeaways etc) and all night I kept waking up feeling like I was going to be sick and had tummy pains.This morning I felt better so I thought I would try cereal for the first time in a month or so. I had lactofree milk (because I thought maybe it was the lactose that was the problem) and 1 and a half weetabix cold (plus 2 spoonfuls of sugar). Within an hour of eating it I was rushing to the loo with gripes and an upset stomach. Once I'd been I didn't need to go again but I have been left with really bad lower stomach pains now and my tummy still feels off.Now I'm confused as to if I'm intolerant to dairy or lactose? I know it's not wheat as I have toast every morning with a dairy free spread and don't react. I can also eat a bag of cheesy wotsits and be ok. But if I have anything that contains a lot of milk like chocolate, cereal etc I feel awful.I'm not sure now if to cut out lactose or dairy or any of them as my Dr didn't really want me to cut out either. So confused but I need to do something as can't cope with the continuous tummy pains and nausea (very intense nausea).
