Harry, first off congrats on not drinking and working recovery. Before you get too caught up in all the nonsense about labels, etc. you need to look at the facts. You are off the sauce my friend and that is a huge!!! I don't think you are a "fraud" since getting clean comes from within. You are tackling one demon at a time so I am certainly proud of you.
You have another addiction which you are battling. You will get there but please don't consume yourself with what others think and so on. Focus on you and take the necessary steps to work on your drug addiction. If NA doesn't work then maybe try counseling, rehab, etc.
I don't do AA but I would suggest that you discuss this with your sponsor and focus on continued sobriety and getting help for your other addiction.
Now that you off the sauce you have a clear mind to get the proper help.
Huggs and hang tight friend. Keep posting and sharing here. There is so much info and we all support you.
