Yes, I was forced to in my late 30s, and seems like it's just natural now in my late 40s. Looking back, it would've been easier if I cut way back on the caffeine, stopped work way earlier (rather than working at 8pm), and just worked on converting slowly by slowly changing my habits. Alcohol also impacts my sleep. I also found my eating and exercise both had huge impacts on my sleep. All these things should've been obvious, but I only noticed after they had to change for other reasons. I took a job in my mid 30s that required me to get up around 6am. It took my 2 years to adjust, it was brutal. Then I had kids, this ruined sleep for nearly a decade. Then, just as they started sleeping in, I wake up with the sun, no matter what. Luckily I seem to need less sleep now.
