Depending on the causes for the urges, tools in the toolbox, audio recordings you can redeem with coins and download, and reaching out to friends or mentors on GYE when you have an urge are probably better options. Regularly reading the book TBOTG and the F2F program will prepare you ahead of time for urges that come your way. The emotions during an urge are intense and it is often difficult to think logically and overcome them by reading the book at that point but if you find TBOTG useful during an urge then go ahead and use it. I can see it working for some people.
