If I was in desperate need I'd work 7 days a week, 12 hours a day, and do all sorts of questionable shit. Including those random medical tests.
That is just alright as long as you can still sleep 8 hours a day, and you have time for your self. I know that is not balance but you are making money so that's it. Always remember to take care of our help so we can still continue to make money with a good health.
