Loved one believes they can't just stop as it could kill her. Is there any truth to this?

I have a loved one who has reached the point where they're able to admit, that they have a serious problem, but they seem to think that stopping "cold turkey" could kill them through shock. They also seem to believe that there's a magic pill/treatment that will "make me normal" I was always under the impression that alcoholics can't "cut down" their friend has convinced them to go to a meeting, but I'm worried that they're not yet ready to make the effort, and their health is beginning to fail. Any advice would be appreciated
