I can usually wait 2.5-3hrs between peeing (unless I get a severe urge) but sometimes get a strong urge to go after an hour or so. Is 1.5-2hrs to long to try and hold on?
I successfully bladder trained a couple of years ago, in the first week I aimed to hold for five mins to fifteen mins depending on the severity of the urge, I would up the time weekly by another five to fifteen minutes (my urgency was severe) by week 5 or 6 up to two hours was common for me and I had no problem. My doctor also said this should be fine!!. Although coffee or alcohol won’t help when training!!. Bladder training is so worth it!!. Keep it up you should be fine!!
