In 2020 I started getting this weird perpetual minor unsteadiness. Like I could not stand still, I sort of swayed, or at least it felt like I was swaying. My doctor said it was too minor to really be anything, I was fine. I couldn't shake it. When this started I was going hard, 5ish hours of sleep, 3 miles on a treadmill, work, then 5ish hours working on a new deck on my house, then sleep, rinse repeat.
A few months ago I started doing one meal a day fasting. I noticed my weight slowly creeping up and wanted a change. A side effect has been my sleep has gotten much better. (I eat lunch typically) I sleep 7 hours easy and even when I wake up I feel like just laying there some like I am a teenager again.
A few weeks ago it occurred to me after nearly two years, the unsteadiness sensation was finally gone. Not sure if its the calorie restriction or more sleep, but I am not complaining.
