Yes! I had people tell me early on that the feeling would fade...that it was a "pink cloud" of being newly sober. I have found that to be a total crock of shite. I recovered my zest for life that was lost to addiction for a very long time. That feeling never ever has to go away. Anyone who tells you that it does is sadly mistaken.
Doesn't mean there aren't super hard times. There are. But there is great satisfaction in getting through them without being dulled. It reinforces that I am strong, smart, and capable. Something I never realized when I was addicted. Something I'll never let go of again.
High on life? Why yes I am! Lol
