A. I generally take my cheap Android phone to bed with me and check the time before closing my eyes, then check the time when I wake up. For really rough days, as backup, I will ask my sons if they know when I conked out.

B. Instead of tracking your RLS, I suggest you treat it. There are studies suggesting that iron deficiency and B vitamin deficiencies can be culprits. That helped with mine, though I have known other people who benefited from other supplements.

C. I highly recommend you start a journal. A written record of health stuff is a hugely valuable health management tool.
