Thank you all for your comments.
The beginnings of my incontinence were difficult because I didn't know how to protect myself. I can't count the number of brands and protections I tried at the time. I was fed up because I had the feeling that there was no effective protection for mobile and severely incontinent people. Since then, I have much better control over my daily life with the Northshore Supreme. I stress a lot less and I no longer hide at home. Generally, I have the opportunity to change in the middle of the day but sometimes I underestimate my urination and I sometimes leak. This weekend I followed your advice and wore a Megamax every day. I haven't had any leaks but I have a hard time staying in the same wet diaper for so long. I would like to try Northshore panties but they are impossible to find in Europe. To try, I ordered 2 PUL panties on a German TCSB site. one for the night and one for the day. I don't know what to expect but I hope to find some extra protection.
