Tommy Lee\u00a0refers to his experience with addiction as \u201con and off\u201d substance dependance \u201cfor a long time.\u201d After a four-year period of sobriety, he\u00a0most recently went through a phase of drinking two\u00a0gallons of vodka a\u00a0day. \u201cI go through these phases where I just want to live a different life and fuck all the dumb shit,\u201d he recently explained to Yahoo Entertainment. \u201cAnd then I decide, \u2018You know what? I don\u2019t want to live like that anymore.'\u201d Things went downhill during his last tour with\u00a0M\u00f6tley Cr\u00fce, where the drummer says he\u00a0\u201cliterally did nothing\u201d and would \u201cjust fucking drink.\u201d \u201cI didn\u2019t notice it until towards the end of it, when I was like, \u2018Oh dude, I\u2019ve got to stop. This is fucking insane.\u2019 Like, I was drinking just out of boredom,\u201d he admitted. \u201cI would just wake up and be just building just all vodka and just a little eyedropper of cranberry or lemonade. I was drinking two gallons -- not pints, not quarts, but gallons, the big-handles -- a day," Lee revealed. \u201cThat\u2019s fucking crazy. \u2026 I just realised, \u2018Whoa dude, you\u2019re drinking enough to like, you could probably die.\u2019 And it wasn\u2019t even fazing me. \u2026 I just became sort of immune to it.\u201d That's when he decided to go to rehab. Now, Lee's been sober for nearly a year; however, he acknowledges it's a day-by-day process.\u00a0\u201cI don\u2019t know if it\u2019s a forever thing, but for now, I\u2019m not drinking vodka today,\u201d he said. Lee's putting out a solo album,\u00a0Andro, on Oct. 16. Read\u00a0SPIN's\u00a0recent interview with the drummer here.
