Adult bed-wetting

Patient: Hello doctor,well i have been experiencing bed-wetting as an adult (21 years) for quite a while now(for around 5-6years).I am a college going student and its embarrassing,when i realize that i continue to wet my bed like almost 2-3 times a month(only at nights) ,and i am awaken by the warm feeling from the wet clothing.Some episodes are preceded with a dream,that creates the urge to urinate,and i end up wetting my pants without realizing the need to go to the washroom.How can an overcome this problem doctor?
