In some ways I feel better, in some ways not. Like kitty face says,
work did make time go faster, mostly because
at work I was less self-obsessed (don't get me wrong, you must be self obsessed to do the treatment) and more distracted from how crazy treatment can get. I also am sleeping less well because I'm spending more time in bed and have less activity to tire me out.
I think it's a toss-up and depends on the nature of your work.
