Will persons who experience alcohol withdrawal symptoms have to undergo addiction treatment?

I have a friend who was an alcohol addict. She stopped 2 days ago and I think she's experiencing withdrawal symptoms. She's been having a hard time sleeping, and when she does sleep, she gets bad dreams. She experiences nausea a lot and has clammy hands. I told her she should get herself treated, but she doesn't want to. Is this normal?
