I can see by the time stamp on your post that you were awake in three middle of the night. You say you don't know how much deep/restful you're getting ... Would a Fitbit help? I got one a couple of years ago, just a simple one, initially because of my blood pressure and pounding heartbeat. Amongst other things, it's really helped me to track my sleep patterns. For example, I've been floored since Friday (interview on Thursday, followed by negotiations, dog to vets, daughter had a mishap) and I'm just completely exhausted. It's useful for me to track my sleep patterns and heart rate at this time. So I can see I slept badly on Wednesday, Thursday and Friday; but I can also see I was doing ok with relaxation. Saturday and Sunday, much better, yet still knackered. This is telling me I'll be ok today, however, I could do with a couple of early nights.
Might not be useful for you, but I really like the way my Fitbit acquires data that I can then use to reflect and / or in medical appointments.
