They get up really early in the morning to get to where they are going to shoot, have make up put on them, talk to the crew and the person or persons they will be doing a scene with. Some even do full days leading up to pretty late at times. This what the porn insdustry, movie industry, tv industry and music industry have in common. Get up at stupid times, get the makeup on, do what they do which can take all day and then go home and don't have much time for themselves. This is why a minority of the people in all of those industries, end up becoming depressed, turning to drugs and get treated like crap etc and again that's what happens in all entertainment industries not just porn.
