Problems with sleep seems to be, from what I've seen, the only valid concern with regards to caffeine intake. If you are trying to sleep better, start there. What's your total daily caffeine intake, and more-importantly, do you do anything to consciously restrict/eliminate it after about noon on any given day?
The other advice I've seen on sleep is to get your body into a regular daily pattern. To start, you need to get away from all electronics (which includes, unfortunately, reading and posting on this forum
) for 30-60 minutes before going to bed. Then you go to bed at a set time, whether or not you are tired, and stay there until morning. Then you wake up at a set time in the morning, whether or not you got enough sleep in the night.
Repeat every day until it gets better.
Like 5:2, it's very simple and straightforward to describe how to do it, but in practice it's much more challenging.
