How often during a week do you make breaks?

[friend_]

I am 100NL full-time player.
Usually I play everyday.
And although during last several weeks I have been running well, now I feel a very strong dislike to seat and play, despite the fact that my session costs me about 200-300$.
Yesterday I felt the same feeling, but I said "lets play 100 hands and then I will be able to give it up", but during these 100 hands I've lost about 150$, wich brought me a very strong motivation to continue to play.
Today I want to make a break, but I'm feeling guilty: "You are in a good shape, why do you want to loose money are not playing?"
So, how often do you make breaks during a month? Is it possible to play month by month without breaks?
