"So brave. So strong. Keep going!!!" one person wrote.
"Looking good! Sounding good! You got this my friend! Take care of yourself! You are on the right path," another added.
"Happy to see a positive change inward and out," a third fan wrote. "Good luck with sobriety and a happy healthy future."
Another commenter noted that it was "obvious" that Jackson was going through withdrawal while on the CBS reality competition. The viewer pointed out that Jackson displayed erratic behavior and snuck food in the shower in an attempt to fill the void that drugs once filled.
"So glad you are walking a new healthy path," the commenter wrote.
Jackson's video came after he posted a clip to TikTok, seen here, which he described as his most "terrifying post yet." In the caption to the post, Jackson revealed that he hid his addiction from the world, won the show, and won back his life.
In a video in which he was asked to give a "one-in-a-million" story that he can't believe happened to him, Jackson revealed that he had surgery for a stress-induced blood clot near his heart less than a month before moving into the Big Brother house. Following the surgery, he became addicted to prescription medication.
"Before going into 'Big Brother,' I was addicted to Xanax, struggled with Adderall and cocaine, and I took my last Xanax less than two days prior to moving into this show," he told his followers.
He added that at the age of 23, he "literally" went through Xanax rehab and post-surgery recovery while on national television for 100 days, and went on to beat 15 people to be the winner of Big Brother 21 in the process.
Jackson was one of the most polarizing players in the Big Brother house that season. But not only did he win the $500,000 grand prize, he also exited the house with a serious girlfriend, Holly Allen. The couple ended their relationship last summer after a year of dating.
