I did fine without taking a pause between two blocks of three months. Most of the good stuff started to happen during the second two three months block of my first run anyway. If you crave listening to it, do it.
Quote:This program is designed to be used in blocks of 3 months at a time. You can use it for as many such blocks as you like, but you must use it for at least one block of three months at a time. It is recommended, but not required, that you take a week off between each block of 3 months you use it consecutively.
