Drinking excessive amount of water during day reduce nocturnal emission? (by the way none of my dreams are related to sex when i get to remember them)

Won't help much: Drinking very excessive amounts of water daily can be dangerous to the kidney, although this takes- alot of water. It is unlikely to help the nocturnal emissions (wet dreams) unless it does by waking you up. Nocturnal emissions usually persist only for a fairly short time during adolesence. They can be reduced by masturbation or even some anti-depressants can prevent ejaculation.
