Urge Jar With My Clients?

I’ve been using the Urge Jar for months now & LOVE it! I am 12lbs down (7 away from my goal weight) & feel like I am finally the boss of my urges! Haha! They don’t freak me out anymore & I almost welcome them, so I can fill up my jar lol! I am a Coach as well & am running a weight loss group in the next month. I would love to use the Urge Jar technique & teachings with them! (Of course giving Brooke credit) Is this okay? What is the procedure for using her tools with our own clients? Thanks!
