Hey, Erica! Nice to talk to you again! 

>  I will never ever work a 40 hour salary job but I probably have a 50-60 hour week when it comes to productivity and creativity. 

I am pretty sure that your productivity is exactly because you don't have a salary job. Amazing things happen with one's work capacity when he or she is doing what he (she) wants in the way he (she) wants it! 

> But life is unfair as we all know.

Yeah. Sadly this is a very tough lesson. Especially when you learn it due to someone getting ill :/ 

> It soon will be over and then the nights will be yours again.

I hope he starts sleeping more soon. But I try to have the right attitude. I say to myself that I have been sleep-deprived so many times before because of heavy workload, stress, ext. Now I have the sweetest reason not to sleep and this is so much better reason to lose my sleep than stress is for example.
