Doesn't feel like work at all. In fact, I half expected to bump up because I had about 24oz of tri-tip with a caesar salad last night around 8:00pm. I think what is doing it is for that last several days, I've only had one meal a day so my IF window has been closer to 22:2 than 18:6. Not that I planned to tighten my IF window but I have been so stressed with prepping our house to get it listed and work and a class in Machine Learning. Pro-Tip: If you have a full-time job and you are taking an online class don't go looking for a new home and certainly don't make an offer on one contingent on the sale of your current one. The only saving grace is that my kids are old enough to be helpful so my wife and I are not trying to do it all alone.
