You have to want to quit drinking, and be ready to do it. If you are thinking of quitting because your Spouse, your Mother, your Probation Officer, or some other person wants you to do so, your chances of success are negligible. Of course, it's great to have the support of other people, but you have to be ready to quit yourself, and be doing it for yourself. Set your quit date, and stick with it. It could be today, tomorrow, or the day after the Special Event that you're already committed to attend next week.
Any day is a good day to make a new beginning.
So don't pick a date too far in the future. In the meantime, see the doctor and obtain your prescription for Naltrexone. You might also want to attend some group meetings, and educate yourself about the medication. When quit date comes, take your Naltrexone. You should feel your usual cravings for alcohol begin to dissipate within a couple of hours.
