NOTE: not a method to get to incontinence, just a question about what you would do if there was a "safe" way to obtain it.
Imagine there’s a drug that causes reduction in bladder capacity and sensitivity, with no other side effects. Such drug is tasteless and odorless, water solvable, works in a cumulative way and its effects are irreversible. First symptoms, usually after roughly a week of constant assumption, are similar to those of an overactive bladder. After two to three weeks, bedwetting happens more often than not and severe daytime dribbling can happen while lifting weights or sneezing, even without the feeling of full bladder. It takes one or two months, depending on the subject, to reach complete loss of control.
Would you ever consider trying such drug on yourself or feeding it to someone else (aware/unaware of it)?
