Bingo! Yeah, this is what I was getting at. Agree with you above. New pathways (habits) are important to establish so long as we're mindful they don't override the old ones. It's a matter of choice. And it's oh so easy to slip up! Especially when we're wired to take the easy route or the pleasurable route (or both!), ie - weight loss/weight gain.
Don't you find it interesting that limerence isn't pleasurable? Quite the opposite, it brings misery and emotional pain despite the dopamine? I find it absolutely intriguing.
I'm not disagreeing with you btw, and I certainly don't know all the answers, in fact, other than overcoming limerance I know zip! The more I learn, the more I don't know!
