Shay, thank you for being a supporter!!!!
I would suggest that you (or he!) start a thread in one of the other forums here (Share Your Busting Stories is a good one, even though you probably don't have a busting story to tell). Let us know -- as specifically as possible -- what he's doing for his CH (meds with dosages; other treatments); what seems to help and what doesn't. There are likely to be a bunch of things he can do to make his situation better. Isolation is very common, with many underlying factors, but knowing that his CH is more manageable is definitely a very good way to start changing that.
