@SusantaC What helped me in that situation was actually another habit I tried to cultivate. I was chronically going to bed way too late, so I actively forced myself to go to bed one hour early to wind down and get tired by the time I actually have to sleep already.
Then I read that beinng on your phone was preventing that sleepiness from setting in, so i forced myself to read physical books instead. It somehow stoked my passion for reading again. Now I'm looking forward to my one hour undisturbed me-time in the evening.
@ceral Thank you for telling me this. I will give it a try.
