My brother is schizophrenic so I have plenty of experience with getting mental health care for the unwilling. This does sound like classic bipolar disorder with just a couple of exceptions. The first is that it is extremely common for people with bipolar disorder to abuse alcohol as a way of self-medicating. The second is the lack of mention of major depressive periods.

You can't just committ him. Well, actually you can in some cases, but it doesn't do much. In most states if he is judged not to be an immediate threat to himself or others they can only hold him for 72 hours and then they have to let him go. This isn't something that gets better on its own, so good luck to you.
