With friends like ours who needs enemies!
I think, myself include, that a lot of alcoholics go through a period of losing friends when they quit drinking. I didn't really have a drinking buddy crowd but find myself currently not speaking to two. Well, they're not speaking to me, at the very least.
You have to put yourself first, emotionally speaking, and if some people don't like that your sobriety is too important to risk on people who don't treat you very well.
