OH! And I'd like to add..
some clinics will allow him to sign a release form that will allow you to call and get whatever info you'd like about how he is managing there.
You can just call and confirm his dose, stuff like that.
My fiance did that in the beginning for me because like you, I was pretty uncertain about the whole thing.
I have only called one two occasions, but it helps ease your mind a bit.
Some might feel that it is a bad idea, or whatever. I don't really care what anyone thinks about it because it was my fiance's idea, he did it and THEN informed me about it, and it gives me peace of mind knowing that I can call there any time I have doubts and confirm that he is still going,what his dose is, and if he has "dropped dirty."
Something to discuss perhaps.
