If you don't have bad withdrawals, they will probably recommend outpatient treatment. Maybe 3-4 nights a week for a few hours with meetings in between. Follow it through to completion or your insurance will not pay a dime on it. The quality of these programs can vary a great deal, in my experience. Choose one with a good reputation that your insurance will pay it's share on it.
Go ahead and seek professional help now and don't be surprised if you have to go back again. It took somewhere between 1-2 years before I stopped thinking about it and craving all the time. You might have to make some changes in your lifestyle. No more bars, no hanging out with the "friends" and girlfriends you used to drink with. There is so much more to life than getting drunk!
Remember, there is not enough booze in the world to make people like us feel better. It only makes things worse.
Whatever happens, do not lose hope. You can always get back on if you fall off and don't rule out AA. I don't go to meetings now but it helped me the first couple of years. Don't let the religious stuff be a deal breaker, it is free help any time you need it. Take what you can use from it and leave the rest. You might even like some of the people you meet.
If you need to talk to someone, feel free to PM me.
