In the light of the physical demands of performing in theatre Paige has said "Musical theatre is the hardest thing any actor will ever do. You become obsessive about sleeping, eating the right food, not speaking and giving yourself vocal rest and keeping exercised". Regarding the pressure of having to be in a fit condition to perform in theatre each night, she remarked "you wouldn't want to read the letters people write when you're off and they're disappointed – it's so awful, the guilt one feels for not being there". As part of a rigorous routine before musical roles to look after her voice, Paige stops eating dairy products and drinking alcohol and works hard on her fitness. After about three months into the production when her voice is tiring from performing, she withdraws from her normal social life, sometimes only communicating by notepad and fax. She never reads her reviews, finding that it is not helpful to hear too many opinions of her work.
