Hi Brigitte,
I so understand your feelings. I was/am a lifelong IBS/IPS sufferer. I have never known a time in my life where I was/am unaware of my bowels. ☹️
Nowadays I cope with this pouch by taking Imodium at breakfast, dinner and bedtime.
my pouch is quiet from the morning until the late afternoon as the first meal of the day has transited thru my system.
eating no later than 6 PM has also allowed me to sleep thru the night as my last BM is typically at 1 am.
I think you will find a lot of the tips/suggestions useful. It took months for my body to adjust and for me to figure out the food, medicines and schedule that worked best me.
