Former Disney child star Shaun Weiss, known for his star turns in classic flicks such as The Mighty Ducks and Heavyweights, for years was known for his chaotic, destructive, drug-fueled behavior, among which were several arrests.

Weiss was again arrested for breaking and entering a couple of years ago and accepted help to get sober from his crippling drug addiction ... and it's heartening to see that, two years on, he's still sober and is looking a whole lot better:

"The Mighty Ducks" star Shaun Weiss has celebrated a two-year sobriety milestone in his battle against methamphetamine addiction with an inspiring transformation picture.

The 43-year-old former child star, best known for playing Greg Goldberg in the Disney comedy franchise about a misfit hockey team, became unrecognizable at the height of his addiction to crystal methamphetamine. He was gaunt, lost most of his teeth, and made headlines for multiple arrests.

On Wednesday, Weiss took to Instagram to share striking before-and-after images to highlight his commitment to becoming sober. In the first image he appeared emaciated and disheveled. The second photo showed him smiling and looking healthy.

It's a wonderful thing to see:

Major propers to Goldberg the goalie!

Addiction is devastating ... keep it up and don't let your guard down my man!!
