Miniar, congrats, and you're looking great.
I know what you mean, too, about all the stress that gets removed, much more than you were aware of. That's precisely what happened with me. It was a major life-changer, in every positive way. If this is a post-op high, well... it's been a year since my surgery and it hasn't faded. If anything, I feel better and better.
So, again, congratulations.
