This is one of those things you just have to try and see if it works. I've quit caffeine completely for a few weeks, and didn't notice a difference in my sleep quality.
I found it didn’t improve my sleep quality or my ability to fall asleep. However - I do feel like I have a slightly easier time getting out of bed now.
I’ve been off caffeine for a year or more. Having it actually makes my stomach slightly upset now. Similar to sugary drinks - I can’t do them anymore. Once I gave them up - I couldn’t go back.
Actually for me I sleep better at night with caffeine in the morning. I find it helps with having a proper active / rest cycle, i.e. concentrate energy and stress during the first part of the day so I can start to wind down in the afternoon, instead of hovering around mildly stressed all the day and the evening.
