Same. I don't drink caffeine after noon and I have a much easier time maintaining a functional sleep schedule.

I had a older relative who often complained about poor sleep. I asked if they drank caffeine in the afternoon and they scoffed at the idea it could be the issue. But I have noticed they are not drinking caffeine late in the day now, and the complaining about poor sleep has ceased.
