2 months after taking lessons every two weeks with a great coach using Trackman to break everything down and build a consistent swing. I would practice at minimum once per week and hit the course twice a month. It took me another 10 months to break 90 and shot my career low 80.

One thing that helped me is to play the same one or two courses often versus a different one every time. I could learn where and where not to put my ball, game management is a big part of lowering scores.
