Welcome WhatsGoingOn.
By giving yourself a future quit date, your mind is giving you permission to drink as much as you want up until then. Why not quit now. Today.
Do yourself that favour.
My drinking was as you describe. What helped me was changing my routine, keeping busy to distract me through "booze o'clock".
The first few days felt like having the flu as my body withdrew from my daily drinking.
There are plenty of recovery programs out there to help us. A lot are online if attending a 3d meeting is not for you.
Wishing you all the very best.
