The longer I stay clean, the more the world just opens up with possibilities and hope. But it's so hard to remember that. And I guess that's the problem. So today I wanna remember. Let me tell you what happens: It all falls down. Just like that. Every time. In his bestselling memoir Tweak , Nic Sheff took readers on an emotionally gripping roller-coaster ride through his days as a crystal meth and heroin addict. Now in this powerful follow-up about his continued efforts to stay clean, Nic writes candidly about eye-opening stays at rehab centers, devastating relapses, and hard-won realizations about what it means to be a young person living with addiction.
