Hi and welcome!
As Dan said only you can decide if you have a problem. But I will say this for thought, normal drinkers don't think about thier drinking. Normal drinkers don't have that internal turmoil about their drinking. Normal drinkers, don't binge, black out, throw up, and get up and do it all over again, be it the next day or a month later.
Should you decide, you WANT to quit, you have many options. AA has helped me and showed me how to remain sober. It's a good feeling to be around people like me, that understand. Al-Anon is for family members of alcoholics. You qualify there as well.
Whatever you decide, we're here to listen and lend support.
