Yep I do all the time, although thankfully since I built my e-bike, it happens less often. Some mornings it's just so cold, or I stayed up too late, or overslept, or feeling sore from activities from the previous day (generally happens when I work on my car and have to lay on the ground for extended periods, or stand up for extended periods, or from yard work etc.), or whatever else.

Over the last 37 weeks (since April) I've averaged right at 100 miles a week, over 3,700 miles total. It normally takes me commuting 3 days a week to get 100 miles or more for a week, and so far I've been doing pretty good in recent months.
