i relapsed last night and smoked heroin I got .3 of black tar I smoked pretty much all of it . I was up all night slept for a couple hours and when I woke up I had I massive headache. And I was vomiting. I smoke another couple thought it would make me feel better. But now I'm throwing up more and shaking and I can't sleep. What happened to me and am I going to be ok? I want to sleep but afraid I won't wake up so I am freaking out.
