We all remember Jason Wahler as the resident bad boy who broke Lauren Conrad's heart on Laguna Beach and then a few more times during their run on The Hills.

After being on the hit TV series, Jason had a string of drunk driving arrests and a few stints in rehab. But things have changed drastically for him since then and he just recently celebrated 1 year of sobriety.

"I wanted to make amends with Lauren," he says of his ex, who he recently contacted. "She was a big part of my life and there's stuff that happened in the past with my drunken ways that I needed to address. She's an incredible person and so supportive of anything I do to stay clean."

Conrad was "impressed" with his achievements in sobriety and "shocked at what I'm doing for work." (He is working as a mentor and sober companion at National Therapeutic Services.)

"I needed to humble myself a lot," he continued. "A lot of people knew me before all the bad stuff, and thankfully I've been able to rekindle a lot of my old friendships."

Of his new life, Wahler says,"I think being clean and having my boundaries and my limitations, I have a much clearer head."

Lindsay Lohan plans to stay on the straight and narrow for the REST OF HER LIFE -- telling friends, she's serious this time ... no drugs, no booze, no breaking the law ... ever again ... PERIOD.

Sources close to Lindsay tell TMZ, the actress had an epiphany after her sentencing -- and is completely at peace with the judge's decision ... community service, fines, counseling, shoplifters alternative class ... the whole package.

Technically, Lindsay is REQUIRED to stay sober during her formal probation -- which ends after she completes her 480 hours of community service -- but we're told, it doesn't matter ... Lindsay's committed to sobriety for the long haul.

One thing ... Lindsay does take issue with the three-year probation itself -- telling friends she doesn't think she deserves it -- but que sera sera ... she has learned to accept her fate.

Bottom line -- her friends are adamant ... Lindsay has learned her lesson once and for all.
