f.lux has been very nice for browsing in bed with my PC, and I am planning on the Pixel 2 that has the blue light reduction soon. While I am fortunate to not typically have difficulty falling asleep, if I am not tired at all, I can start a vicious cycle of watching videos on my phone because I'm awake and being awake because I was on my phone.
Teas also relax me, I enjoyed a tumeric tea last night and may do the same tonight! Now if only I was better at getting out of bed in the morning after the sleep!
