Psycho-somatic reactions are no joke. I still remember taking my brother for an infusion. We go downstairs (why the fuck do you put pediatric oncology in the basement???) and as we get out of the elevator he pukes in a trash can. "You OK?" "Yeah, just thinking about the treatment"
I tell the nurse about the can as we are checking in and she just sort of shrugged it off and said housekeeping does regular rounds on all the trash cans.
He didn't have his hair back yet, but he lead the Congo line at my wedding, with a champagne bottle in hand
