My boyfriend suffered with sleepwaling when he was younger, but for the last two years has not had any problems with it. Last night whilst asleep he sat up screamed and then tried to strangle me, he has agreed to make a doctors appointment but is unable to get one for two weeks. What are the options that will be open to him once he sees the doctor. he is scared that he will do it again, he is also terrified of what the doctor will say and i just want to be able to offer him some support.
