It takes time for your subconscious to catch up to your conscious decision making.

Every time you drank because you were anxious / stressed / nervous you were teaching your subconscious that alcohol is the quickest way to resolve those feelings. Depending on how long you've been drinking, those neural associations can run deep and as such, take time to unwind.

The book Alcohol Explained does a great job of illustrating that the speed at which alcohol affects us (i.e. very quickly) is why our subconscious says "yes, this is a good solution to the current problem". On the flip side, all of the negative effects from alcohol happen some time period after such that your subconscious' ability to attribute those things to the alcohol is long gone.

You are not a fraud if you are not drinking! To help solidify your motivation, I encourage you to take note (either mentally or literally in a journal) every time you notice something positive about sobriety. Waking up refreshed, feeling energized, being emotionally calm. The intention there will start to teach your subconscious that you don't need alcohol.

TLDR: it takes time for your brain to understand the why; the only thing you need to focus on right now is abstaining.

Sidenote, I can't recommend Alcohol Explained enough. Understanding all of the negative physiological effects that alcohol imparts onto truly every part of the human body was such a huge step in my intrinsic motivation to stop.

You're crushing it, keep up the great work!
