Ok, obviously I love running...
I won't state the obvious here, I'm definitely a fan of a runner's high.
As far as what you describe, this is something I've struggled with myself, as I've seen it as separate.
Truthfully, though, what I've found is laughter. If I'm at a place where I can laugh with someone I love, that replaces the high ten fold. My happiest memories are wholesome, silly moments, where my husband has made up a song about something or I've done something (sober!) ridiculous. And those moments just don't make themselves known when I've been drinking.
