When someone decides to put the effort into living their life sober part of that healing means setting boundaries to protect their own effort. So, that means disconnecting with friends that still engage in alcohol use. You need to focus on YOUR life and that means changing the people you associate with so as not to get sucked back into the lifestyle you are trying to change. It's better to surround yourself with others who understand the challenge and can support and respect your efforts to make this important change in your life.
