It's always hard giving support to someone who's coming off an addiction, especially when they're quitting two highly addictive substances @PeppyPatti , so the fact it's rough isn't a reflections on you, it''s the nature of the problem.  You both may find it less difficult with the support of a drug and alcohol counsellor or psychologist who deals with drug and alcohol issues. 

I had an uncle who was a drug and alcohol psychologist, and  a friend of mine was a drug and alcohol counsellor, so I know there are some very good ones out there...and there are support groups you could go to such as Al-Anon and Naranon for the families of people dealing with their addictions.
