Are alcohol withdrawal symptoms signs that a person really needs addiction treatment?

I have a friend who happens to be addicted to alcohol. Since she stopped drinking two days ago, she has been experiencing what I think are withdrawal symptoms. She’s having a hard time sleeping, and when she does get to sleep, she experiences bad dreams. She’s also nauseous a lot of times, and her hands get clammy. I’ve already told her to seek medical help, but she’s stubborn and doesn’t want to. Will this go away?
