Does allowing an urge have to be uncomfortable?

In Urge Call #2 Brooke says that allowing urges should be uncomfortable; that when we put a gem in the jar we’re probably feeling crappy. I am finding that I don’t put gems in the jar because I dont feel restless etc. I am sticking to my food plan 100% and I definitely have the urges to overeat like I would have in the past (ie. after I finished a meal, I’d always grab extra somethings) but as soon as I notice it now, I kind of go “hmmmm I see that urge” and then I don’t eat it. The question is if I’m missing something since I really don’t feel crazy negative feelings. It’s like the awareness combined with the commitment to the plan is enough. Thoughts?
