I hear ya!Â
If you are feeling ill effects, you need to look at your caffeine intake.
I used to be fine. About a year ago, I noticed the same thing. I find that if I stop around 2:00 P.M., I sleep fine. You may want to experiment with what your optimal "quit time" is. I saw a study about how we metabolize caffeine. It recommended 2:00 P.M., and worked great for me.
Pleasant dreams! 😴💤
