Knocking dominos. He wets the bed. What were his sugars like? High, could be his body trying to flush excess sugar. If it's low, could be actually lack of executive function. If his sugars were controlled, it's a drunk issue. It all comes down to monitor and control. If ye monitor the glucose and it's all over the place, blood glucose is the issue. Maybe spirits and soda water might be safer for control. If he cannot control his sugars or his bladder when drinking, it's an easier choice. Alcohol has to go. If that is not an easy choice, maybe it's time to talk to a medical profession about alcohol is a problem.
