I haven't written up about my 100+ hour weeks specifically, but from 2008 to 2012 I did literally nothing but work and sleep every day (7 days a week). Even eating I did while answering emails, etc. Sleep I didn't skimp on (7 hours average a night, but that is my norm even now). My day would start at 6.30am (sometimes earlier if I needed to call a customer in a bad time zone), eat breakfast while dealing with emails, etc, go to work around 8.30am (I luckily had a short commute), work until lunch, work on my business over lunch, work more and come home around 6 pm, eat dinner and work, then round out the day with some more work, and finally go to bed around 11.30pm (sometime later if I need to call customers, etc). Weekends were much the same except no commute. No I didn't get sick and physically I could have sustained it for as long as I needed, the biggest side effect was my judgement started to become detached from reality. It was a very slow and steady drift, but in hindsight I can see my decisions were not always the best. Nothing catastrophic, but not the best by any means. This was the cost of building a business when you have a family to support. I now get to spend a lot of time with my family, and while it wasn't easy, I still think it was the right decision. Four years of very, very hard work has avoided 30 years of hard work.
