Watching with interest as my sleep seems to be perhaps the single-most problematic factor for my wellbeing currently...
I recall I had an uncharacteristically decent patch last summer where I was getting to bed regularly at 11 or before, sleeping through and feeling pretty good when I got up consistently at 7ish. I remember this corresponding with a notable absence of anxiety / generally a much better state of mind.
Now I'm often awake until well past 12, usually get up at least once for a leak and often struggle to get back to sleep afterwards.. while there's also no consistency from one day to the next. I've spent the holiday catching up on sleep; it's still all over the place but I am gradually feeling better for i - serving to illustrate how much running a constant sleep deficit has been hammering my mental health.
I'm aware of the need for better "sleep hygiene" at night, which in itself is a bit frustrating as I really love some mindless time buggering about on the net at the end of the day to decompress. I'm less sure how to combat the early waking - the need for night time leaks is going to become more inevitable with age but allergies also play a part - when I've had particularly bad reactions to food I've been up five or six times in one night..
The waking is only one issue of couse - the other being getting back to sleep afterwards; which I think is torpedoed by anxiety as silly O'clock in the morning seems like a perfect time to ruminate over all the stuff that's currently going wrong.
