I've had a upset tummy since Friday, yesterday after a bad bout in the morning I went all day without 'going' despite rumblings and what not! However I woke up twice in the night (probably not helped as I went out for a meal last night believing I was on the road to recovery) and I've had bad cramps and and bad bout this morning. Is it normal these things last so long? I've never had an upset tummy before so its all rather a new experience for me! I've just taken some tablets which claim to help although I imagine they just mask the effects rather than address the actual cause.
