Good for you Ali,b/f really does need medical intervention now. Your love and devotion just isn't enough.
I think others have said many times (not just on your thread) that the secret of success with AD's is finding the one that works for you and at the right level.
So the sooner he starts the sooner they can find the one that is appropriate for him and that is good for you both-yes?
For your sake I hope they find the best combo sooner rather than later,it will take time but this will be the first step in the right direction.
You are going to need all the patience you can muster and then some, but I have a feeling you can do this.
As long as he is willing to get the help good for you for taking the step to getting it for him.
Take care of you as well.
