hey 2loaded i always feel weird about answering questions that no one has answered but i also don't like seeing posts just go by with no response. are you under a doctor's care? I only did heroin briefly. i took clonodine when i was on a taper off vicodin. but i would hate to hazard a guess about what you need for heroin withdrawal. that is very serious, and i think you need to be monitored and under a doctors care. good luck.
