How much have you been drinking and for how long has it been going on? I'm the resident expert when it comes to alcoholism and regrets of actions performed while drunk.
Different people would give you definitions of what an alcoholic is and is not; it's not entirely objective. But if you're drinking a twelve-pack of beer in the day and half a liter of vodka (mixed with benzodiazepines) and are not blacking out, you have a problem (the simple fact that you CAN handle that much shows that you've developed a tolerance.
If you feel physically uncomfortable while sober, and I'm talking hands trembling, twitching and convulsions, changes in balance, intense cravings, and the worst flu you've ever had. Have you ever had a seizure as a result of being deprived of alcohol?
If you answered yes to that last question, then I'd say you're heading down a dark road. Don't quit all at once, though, if you feel the dopesickness (withdrawals), you're literally risking your life. Do a hospitalized detox for a few days until you've stabilized because people have died from withdrawal seizures. If you need a crutch, try marijuana and see how it affects you - it's not nearly as bad for you as alcohol.
Otherwise, if you still believe you have a problem, don't check into rehab because real life is not "Intervention" and "A Million Little Pieces" failed to DESCRIBE the rehab center clearly enough for someone who's not been there to understand that it's not a spa or a resort hotel.
Read recovery books. Give the 12 Steps of AA a shot (I did) and if that isn't for you there are also Moderation Management and SMART Recovery which are more about using alcohol or drugs or whatever in moderation. You'll learn to control yourself from any of these things. Go to meetings. Be forward. Talk a lot about your problems, AA usually will at least try to help you. Get phone numbers from people at the meetings, and try to hit several meetings in one week to get to know sober people and gain a support network. And get a sponsor early on that you can call on if you ever need to be talked out of drinking.
I don't think you're an alcoholic. But with the way you're going, you could very well be in just a couple of years. You're sinking, but you haven't sunk so get some preventative help!
