the post below promted this thoughtNow I have read that your IBS should not wake you at night as the gut goes to sleep with the body but what if (as in my case) your digestion and waking patterns have been knocked out of synch? I worked nights for many months and as a consequence I will waken after only about 20mins sleep (usually very vivid dream sleep) then my bowel would wake up also, it would gurgle and make all the weird noises us IBS suffers know only to well, then I would pass wind (from either end) I would finally get to sleep again after this stopped, but it can go on for 2 hrs or more I used to think that i had excess gas but now I believe that my bowel is waking up for short bursts of action maybe once or twice a night.
