It's always hard but the reality is, especially in my case, that every time I go to work I have to do it so it's become part of the job. It's an extra challenge but it's also quite often another extra tool that you have to really think consciously about getting into the character. So while it does require more work, it's maybe even an advantage to a degree because it forces you to switch, to consciously have to jump into and out of the character.
