Convicted money launderer Apollo Nida already got 22 years sliced off his prison sentence, but ironically a DUI might help him shave off a few more ... TMZ has learned.
According to court documents obtained by TMZ ... the "Real Housewives of Atlanta" cast member agreed to a 500-hour "intense" drug treatment program during his 8 year sentence -- even though he's not currently addicted to anything.
Law enforcement sources connected to the case tell us Apollo only got into the program because he has a prior DUI -- and we're told his real motivation is lowering his sentence.
Inmates who successfully complete the program typically get early releases.
Of course, there's no such loophole to help him skirt the $1.9 mil he has to pay back to his victims.
