I'm 23 years old and I wet my bed
Why do you think you wet the bed?
I wet the bed when I am drunk.
It isn't normal for an adult to wet their bed.  You need to watch your drinking if this is the cause.
I don't really think I should be considered an adult.
At 23 years old, you may still be young, but don't you think you should be mature enough to not wet your bed? Your drinking may be causing you to lose control of your bladder. It might be a good idea to cut back on the amount you are drinking.
