Yes. I have found that I laugh a lot more. I love laughing and joking about. I love making people laugh. People laugh at me for all of the right reasons now! lol.
Because I am an addict then even things like laughing used to get me a bit sad and depressed because I couldn't increase the effect through drugs/drink. Like even laughing would trigger my addict mind. That has stopped for a long time now and I have reached the stage where I am really comfortable with 'natures' natural experiences without having any yearning to highten the experince. I am happy now I guess. It's a great feeling.
The only laughter I had when I was still actively drinking and drugging was chemical induced euphora and hysteria. Then just delirious ramblings and laughs. During the periods between binges then there would be no laughter, any laughter that there was would be followed by a depressing yearning for drugs and booze.
Laughter is fantastic medicine.
peace
