I remember reading in one of Joan Collins' books that as she was up for work at about 5am and then worked 12 or 14 hour days. That often it was come home, shower, eat and then read lines for the next day. Then bed very early to be up and do it all over again the next day. I think that was common for people on these shows back then. And if they did have time off from filming they wouldn't spend it watching soap operas they would be going to events, or travelling and doing promo.
