Heroin...Clean....Ice......Now What?
I use to be on heroin bad. Would shoot up 4-5 times a day. After an OD I went to rehab' got clean and came home.. clean for 8 months and started smoking ice. Then shooting it. Today I am on day 3 of being nauseous, getting dizzy spells, and my stomach hurts. I have to take anti nausea medicine so I don't puke. I've smoked and shot everyday for like 3wks straight.. so why would I be sick or feel like this.

Ur pipe drunk. U need to sleep eat and bring your tolerance down. When u get up in the morning eat or drink something filling. Toast, milk, yougurt ect
