"I was back on track, raring to go and then the insomnia kicked in. When you don't sleep, your faculties are not as sharp as they would normally be. My memory has been affected, I'm not as mentally agile as I would be if I were sleeping properly. I can't work because to act you need to be able to learn your lines and I can't do that at the moment. Insomnia is awful. I wouldn't wish it on my worst enemy."
