Hey Husky! Glad you found this place, the people are great and will do what they can to help!
It will be important to be 100% honest with your doctor about your situation, how much you drink/drank etc.. The anxiety does suck, believe me I know, I've been dealing with it a long time but there are meds that can really help to get you through the first week, if you and your Dr choose to go that route.
Don't think about what hasn't happened yet, don't worry about what hasn't happened yet.
Almost everyone has the "I know its going to be unbearable, so I'm not going to even try" thought the first few days.
Sounds like you are taking the right steps in your new beginning. I think being honest with everyone who is impacted by your drinking is important.
So, who has the key to your locked up beer?
