My severe urgency is not regular at all. I can be fine one minute and the next ready to soil my diaper at a moments notice. Sometimes I can last for up to 5 minutes but most of the time not.I've been burned before thinking I had more time only to have a surprise BM when I least expect it. It's safer for me to just wait until release is iminent and just let go. Otherwise it's just to uncomfortable. I use a bulk producing fiber supplement (psyllium/ Metamucil) to keep stool firm otherewise I end up with loose stool (disgusting and really uncomfortable). My question is for those that sometimes get notice. Do you wait it out and just go in your diaper or do you try to hold it. If it wasn't so uncomfortable I would try to hold it but my failure rate is much too high and to be honest, the relief I feel is not unpleasant.
