jack i know how your son feels i am also 16 and have also just started to wet the bed again after almost 5 years of being dry. Like your son i'm also into alot of activites and sports at school. Even if you ask your son to leave some school actitives it still may not help. my doctor had told me if i wanted to drop a few school activites or sports to maybe reduce some of the stress in my life, it still may not help(there was only about a 25% chance that it might). and besides your son would be missing out on the stuff he likes to do. i hope that i was heplfull
