I think it happens less than once a month, and almost always lasts less than a week.
I do wish that I went hiking more often, camping more often, and I wish that I had more social interactions that were free of social and business undertones.
I once felt that living like you currently are was sustainable and that I would be impervious to the long term effects, but now that I have hit the half century mark, I am finding I suffer from all sorts of back and shoulder pain from sitting for extended programming sessions lasting days. I also have rapidly degrading eyesight, and high risk of glaucoma from staring at screens all day every day, and I have other health and digestive issues from not eating regular healthy meals, or drinking enough water back in the day.
It is highly likely that the lifestyle you are accustomed to will turn around and bite you one day. Make changes now so that you don't end up the same as this old programmer. :)
That being said, make time for yourself, all consuming projects will make you discontent with life in general.
