My symptoms are on and off...two weeks great a then two or three days bad. It usually hits me at night. Sometimes right after dinner and sometimes 3 hours after dinner. Last night I thought I was going to die with pain. My pain is usually not severe but this time it was combined with a regular BM and then the total water BM came out. The cramps stopped after that but tummy feels bruised. This has happened many times in the past 5 years. I go on the next day eating safe foods along with BRAT food and my day is fine. Besides the diagnosis of IBS-D do you have any ideas or is this just they way my life is going to be.
