I'm currently in a position where I won't be able to be diapered for a while, but eventually want to commit to bedwetting full time.
So I'm thinking about making a file that encourages excitement at the thought of wetting the bed, but suggests that the next time you wear a diaper to bed you will be a helpless bedwetter. The file would also have suggestions to wait as long as possible before trying that first diaper, because you won't ever be able to stop once you start. The longer you wait, the better it will work.
I thought that, since there's no way to provide negative reinforcement in this situation - unless the user is listening and wearing diapers at night frequently - there's no way to know it will work until you finally give in and put on that diaper before bed. And there's always the chance that it will be permanent, so you may want to wait a little longer, but keep listening. More reinforcement, more expectation, more pleasure at the thought of becoming a bedwetter.
Just an idea.
