I do it differently. Instead of boohooing while I'm writing the character the next day I'll find myself in a general funk. In the same way, if my characters are arguing I'll find myself short-tempered the next day.
I tend to be that way in other areas, as well. I don't watch sitcoms anymore because I don't like myself after I watch them. I get sarcastic and bratty. I quit watching them back when Roseanne was on the air; she was absolutely the worst for me.
