I tried a medicine like Antabuse a couple of years ago. It helped for a while, but it is by no means an airtight measure. For me, it made me think twice when I had cravings, which is good, but after the first withdrawals you'll need a stronger plan for handling those cravings. When your motivation wears off after the first few weeks or months it's all too easy to quit medication, although I guess if you get shots, it might take longer for them to wear off.
A medicine like that makes drinking not an option, but you're gonna need a lot of other options to spend your time on, to build your life. There's much info here on making a sober plan. Try to take the time to make one while you await your doctors appointment. Write down what you'll do when you're bored, lonely, anxious or in crisis. Don't forget thinking of new ways to experience and celebrate happy moments.
