I took a three week break for a recent vacation, after we got back I measured a considerable gain after working for 6 months or more. Listen to your body and take a break when you feel like you need to. I was worried that I would lose what gains I had before the break. However, during our vacation I drove my wife crazy because my EQ was incredible. I don't worry about the breaks anymore, this is a lifestyle change for me that in the long run will pay huge dividends.
