Hi,
It is not usual for a normally placid person, with diabetes, to turn nasty when they are having a hypo...and I guess the same can be said of alcogol. I agree with Sue..if he is beyond the point where you can help him, all you can do is get help...ambulance or police. Please, you must keep yourself safe.....if he is beingviolent, kepp yourself safe...he will eventually pass out. All you can do, is make sure that you keep checking on him...and when he passes out, make sure that the ambulance people are there to sort him out ASAP. I believe that ambulance poele will not endanger themselves either..and will either call for police back up, or let him pass out, before reviving him. I am not 100% about this, as I am only little myself, so have never needed this kind of action.
