That's not a friend that's someone who wants to see you down. He probably was urging you to get sober so he could feel superior to you: the drunk and now that you are he is trying to sabotage you. For all you know, he has a bet going on how long you will last without drinking or whatever.
This man is NOT a friend. A friend would not drink in front of you in early sobriety. A friend would drop in with some sport drinks or vitamins so you can stay hydrated. A friend would spend a quiet evening with you watching TV with non alcoholic drinks. A friend would be concerned about your shaking etc.
I say good riddance to a bad apple. Once you are more ensconced in your sobriety and start doing sober activities, you will meet a new crowd and make some real friends.
