Don't take breaks

I read in a book that taking a break from writing for even one day has disastrous results. I am experiencing that first hand now. Took one day off, as I felt sleepy, and today, I seem to have forgotten how to write. Cant put a single word down. I have lost the link and the continuity, but most importantly, I have lost my characters. Just because I didn't think of them for a day, they refuse to tell me what happened and how they reacted. And as a direct result, I have to write the story myself. And I am not such a good writer. If the characters don't tell me the story, I have nothing to write.

Memo to myself, WRITE EVERYDAY! Getting back into the flow is just so hard, that it's not worth lazing around for a day.
