I can’t stop

I (22) can’t stop. I have a detox center calling me Monday for insurance but I was told I should see my primary care doctor instead. I want to go cold turkey- I’ve been drinking a whole bottle for 2 years. I am drenched in sweat when I sleep (for 2 hours a night). I need sleep and I’m getting upset/angry over everything. I need help, what should I do. Go cold turkey or visit someone to see if I can make it cold turkey.
