I know a lot of authors struggle to get through this, but I have learned to just get up and walk away. When I am writing, I feel as if the characters are 'talking' to me, if they go silent I take it as they, as well as I, need a break. This can be frustrating when I am on a roll, but if I try to 'force' the conversation in my head I end up disliking the end result. Eventually they start back up, usually at around four in the morning, but such is the life of a writer.
