Yep! I did a whole post about it in this thread. I have a couple of other do-less goals along the same lines for various compulsive actions. I’m down to being allowed to ask for reassurance twice per week from five when I started the goal, and haven’t derailed once yet – this is one of those cases where the financial threat worked really well.
(Biting the skin around my nails is one I’m having more difficulty with. Brain: “Argh it’s a hangnail, I’m going to die!”)
