I started keeping a simple note on my phone, just time I woke up and whether it was heat or just awake for no reason. Three weeks of data now. The heat wakes are clustered around the first half of the night, usually before two. The second half is lighter sleep but not the same thing. I brought this to my appointment last week and it actually changed the conversation. Instead of me saying I sleep badly and the provider nodding, we had something to look at. She asked about alcohol and stress timing, which I had not tracked, so I am adding those columns now. No conclusions yet. The tracking itself is the useful part so far.
