If they drop you once you are sober, then those are not friends just drinking buddies.
You say your friends hate your drinking, they are probably worried about your health and maybe you are obnoxious when you are drunk. If they are true friends, they will be supportive and glad that you are taking a step forward for you health.
My best friend is an active alcoholic (long story) and my best female friend is a normal drinker. Those are the only two friends who know I am in recovery (I was a closet drinker, live alone, drank alone). Both of them are happy for me and my getting sober did not affect our friendship.
