Dont let the diaper "stigma" keep you from using them if you need them, it's FAR better to deal with a stigma of wearing a diaper than dealing with the issues if you had an accident and were not wearing a diaper. While it takes some time to get used to, soon you will realize people dont know or dont care that you wear a diaper. Diapers have a purpose and like many others before you, you'll soon learn they just become "underwear" that allow you to go about your life, it does take some time and trial and error but you will develop a routine and learn how to manage your issues and live with the added needs that wearing adds to your life but it won't ruin your life unless you allow it to. As for IBS you might find that many foods trigger your symptoms for me personally if i eat nuts or seeds I have a high chance of an accident the next morning. so look at your diet and try to find the trigger foods your might have.
