Your apprehension is perfectly normal. The nice thing about AA is that there is no rigid timetable to do anything. Keep coming here in the meantime and get things out as you need to. These first baby steps are important and constructive
BTW... I used to shove beers in my laptop case and drink in the men's room between classes in college. Other times I'd have it in my car and go to the parking garage and swill a couple when I had more time. You'd be surprised how common this type of behavior is.. you're not alone.
