Goal to soak my diaper while I sleep

Wife and I have been playing with diapers for some time and I have gotten to the point where I have peed involuntary a few nights. Mostly from too many drinks or a CBD sleep aid.

Main question is, How to I consistently soak my diaper without using the above?

Try a catheter

Before losing my prostate hydration helped but was by no means perfect. This thread reminds me of a rumor going around back many years ago. It was said that a number of AB/DLs wanted to be incontinent. There was a short procedure that could be done to render them incontinent. All is well and good for these folks who had just got what they wanted. Soon some grew tired of the diapers 24/7 and wanted to be repaired. The problem was finding a surgeon to do the repairs. Careful what you wish for, you might just get it.

Perhaps its because I wet my bed for so long, until I was 17, that I found it fairly easy to resume wetting my diapers at night when I returned to wearing them full time, which I did 15 years ago, not because or need but because I had longed go be able to wear diapers without fear or disapproval. I didn't happen right away, but within the first year I started waking up wet and it didn't take long before I was wet most morning. During the long interlude between my late teens and when I resumed wearing my diapers and rubber pants, I was unable to wear more than occasionally or very sporadically, and seldom woke up in wet diapers.
