I know people that used to drink 24/7 7 days a week and lost everything including their health, they are very successful in the rooms of AA as they were at rock bottom which allowed them to completely surrender and choose a new way of living. There is no way on earth that you are in the same position as them and odds are, even if you never stop drinking, that you never will be because it isn't your pattern. You've already identified why you drink, introverted and isolated. Who wants to feel like that? So what are you going to do? Most drinkers do not use alcohol to feel completely different, they may use it for dutch courage or to simply relax but now to change their personality completely! That indicates that you have a big problem without alcohol, as you are normally. If you address your issues with how you are without alcohol you might just not be interested in abusing alcohol that much anymore.
