Definitely see a doctor. And good on you for posting here and seeking help.
I wish I’d quit at 28... it took me until my forties to wake up to the damage I was doing to myself and others with my drinking.
You know you need to stop and well done for coming here and posting. Get help offline too. Good luck with your detox and work out a plan to stay sober. Again, I wish I’d been wise enough at 28 to have worked out I needed to stop. It’s never too late, but you can change your life for the better forever and there is so much in front of you. You deserve to enjoy it,
