i also use goodnites and so do my 3 brothers. when you wake up you gotta go to the bathroom that might help you stop wetting the bed. my older brother does the same thing but when he wakes up he goes to the bathroom even if he is aready wet, even though our room is freezing. i gotta share a room w/ my 3 brothers, but i don't care that they wet the bed and they don't care that i do the same. by the way they are all 15 too, they are my twins. hope this helps.
