I'd consider rehab or counselling if you can't quit using AA and your own devices. You personally need to make the decision to quit though - even inpatient rehab will just be a waste of time and money as you'll most likely be back drinking as soon as you get out if you don't make the committment. There is no "magic" pill or treatment in rehab that removes your will to drink - it just safely gets the alcohol out of your system and prevents withdrawal side effects.
For some reaching bottom is the only way - but you have time now to make the choice before you hit it. You should be very thankful that you recognize the problem before that and try to take action on it. Remember - not everyone that hits bottom gets a second chance either - you could end up dead from a car crash or some other kind of crazy accident while you are blacked out. You could kill someone else driving drunk. Do you really want to roll the dice?
