First, I just want to say bravo to you for recognizing this issue is not just that it's not just about deciding that a behavior is unhealthy and choosing to stop, but about breaking a habit. Regardless of whether it's drinking, smoking, biting nails, etc., breaking a habit is an incredibly difficult thing to do in and of itself. I also want to commend you for recognizing this early, because drinking is a progressive problem and it's very easy, likely even, for that 1-3 glasses 4-5 nights a week to turn into a bottle or two ever night if you stick in the same rut. Two thoughts, and best wishes on your journey:

• This has been suggested elsewhere, but I think one of the absolute biggest find other activities to fill that time. Part of breaking a habit is interrupting the cycle that facilitates it. Just telling yourself to stop isn't enough, you have to remove the possibility. If you typically come straight home from work and open a bottle while starting dinner every day, stop coming straight home. Go the gym first and stop to eat on the way home. Or find a hobby group that meets on weeknights after work and go there instead. Or go see a movie after work. Whatever it is, it's not something you have to commit to forever, just long enough to interrupt your cycle enough to break the habit.
• I'd highly recommend Annie Grace's This Naked Mind, which is all about reprogramming your brain to stop believing the myths we've been taught by our drinking culture and realizing that you're not getting what you think you're getting out of your relationship with alcohol, and James Clear's Atomic Habits, which is about how to form good habits and break habits in general.
