Suggest Remedy For Odd Behavior After Drinking Alcohol

hi, my boyfriend after a few too many drinks, sometimes wets the bed or pees in odd places, like middle of his room or the kitchen? when he is doing this you cannot wake him and the sounds he makes are sounds he normally doesnt make, and if he talks he says strange things that make no sence. should i take him to see a doctor, this has been happening for a few years now? it is very embrassing for him and i dont like to talk about it to him as it is a touchy subject but yeh i want it to stop.
thank you
