Hi there! You are sooo right - great advices, thank you. I think Dennis at first had that problem with Level Two and so he came up with the RI. Yes, one has to be really on the ball and stick to the plan, the instructions, before closing up shop or throwing in the towel.
Nowadays, I find that when I do RI to relieve a particular stressor, almost immediately similar scenes start running - first the motivators, and then the overts. It's quite therapeutic, especially concerning 2D incidents with my husband as the current restimulator/lock.
My particular case always runs from entry into this universe up to now, and backwards and forwards earlier similars to whatever is related to present time stressor restimulator lock. It's quite therapeutic.
Yeah, the biggest no-no I'm usually guilty of is not running enough RI.
I wish you much progress with your practices and resolving fixed postulates.
