Your story sounds very similar to mine, I have been wearing 24/7 for about two years now, and have noticed a signicificant reduction in my bladder capacity and being able to hold in a wee, I consider myself incontinent now, as when I’m not wearing a diaper, I often find after a even little bit...
I’ve found that if the nappy has been boosted too much, and im having an active day with lots of walking around, chaffing can be a serious issue for me, my legs are naturally quite muscular and a wet AB diaper swells up and rubs real hard on them
I have to agree with you, I am a super soaker and find that, what is usually advertised as a 12hr diaper, I’ve usually soaked by around 6-7 hours, so a booster or multiple is a must for me.
