I have been diagnosed with IBS for about 20 years (I'm 37), and for the most part I have all the classic symptoms. However, I noticed on this site that a red flag for having something other than IBS was if you are awakened by pain. Problems sleeping have increased over time for me, to where I'm now at the point where I rarely sleep through the night. Sometimes I can get back to sleep without getting up, but frequently I need to get up for awhile. If a BM is coming on, then I won't be able to sleep again until it happens. A number of years ago I found that I could improve my sleep by waiting until I had a BM before going to sleep. These days, though I still do this, it no longer seems to last for the whole night.Does anyone have any similar experiences? I've had numerous blood and stool tests, and a colonoscopy years ago, and all show no problems.
