Episode during evening walk

While walking the dog we were a block from home. I started to feel tired. My eyes started to get heavy and I wanted to close them. I felt like my legs were moving but I wasn’t totally in control. I thought I could make it home until I got to the end of the sidewalk and decided to sit instead of step down. I couldn’t speak louder than a whisper. I focused on my breathing and eventually couldn’t move. It lasted maybe 60 seconds.

Today I didn’t eat until I had a bar around 6pm. Then we had dinner at 8:00. My only workout today was a light 15 minute walk on the treadmill.
