Scott Disick -- I'm Turning Over a New Leaf ... For a Price (PHOTO)

Scott Disick finally may be ready to get sober and clean up his act in the name of family ... but you better believe he's gonna make a buck off of it.

Disick (or more likely his assistant) posted an obviously-sponsored tweet Monday, writing, "It's 2015, get up! Perfect start to the year. My @BooteaUK teatox from Bootea.com. Time for a cleanse!"

Considering Disick's recent bender in Aspen just a month after baby mama Kourtney Kardashian gave birth ... you have to wonder if it's too little too late.
