Macklemore completely blew up thanks to his fan favorite number one single “Thrift Shop,” but things haven’t always been smooth sailing for the rapper in his personal life.

Having been sober since 2008, he tells Rolling Stone that the past year of success has been a constant battle to stay on the right track.

"The last three months haven't been good for me –- the pressure, the expectation, the lack of sleep, the stress, the traveling,” he says. “I just want to get the f--k out of my own head."

Macklemore struggled with substance and alcohol abuse with heavy use of drugs like OxyContin. After cleaning up his life and going to rehab back in 2008, he teamed up with Ryan Lewis and started really taking his career seriously.

During his trip to SXSW this year, he took Rolling Stone to an Alcoholics Anonymous meeting in Austin, which was his first meeting in two months. “It’s been a struggle the past year,” he admits. “It’s very important to go into the rooms of AA, smell the sh—ty coffee and be reminded that without sobriety, I would have no career.”

Even though Macklemore’s sober life has been a daily struggle, he can’t deny his gratefulness for all the success and where is life stands now. “I spent a lot of my life rapping and not making enough money to live, and gratefully, that’s not the case anymore,” he says. “But not having a foreseeable end date in sight is a little bit scary.”

We don’t think he has to worry too much about all this coming to an end anything soon. Macklemore and Ryan Lewis continue to grow and gain fans, thanks to their music that’s not only about poppin’ tags at the thrift store, but also such positive messages as same-sex marriage equality, which we chatted about with them at the mtvU Woodie Awards.
