Alright. There are a lot of great posts here. But OCitchy...I'm stoked you're going to rehab. It's necessary if you're serious about quitting. People will disagree with me on this, but opiate kicks are the easiest of almost all the pyschoactive drugs avaliable. Yes, the kick sucks if you're a heavy user but letting your body recover on its own its absolutely necessary. Do not take Narcan. You will feel hell. If this is a legitimate clinic, they will likely provide suboxone sublingual wafers. It's a 50% mix of buperenorphine (agonist/antagonist), and Narcan (full antagonist). The combination is good because it allows an easier comedown and it still stimulates the opiate receptors your body is used to using with H. It will still be painful.
Do not use methadone. It's nearly as addictive as H, but with a longer half life...which is the only benefit of using it. That said, you need to go to special methadone clinics for that, which cost plenty. A regular rehab facility should be partially covered by insurance if you have it. If you don't, I recommend going cold turkey. H has an extremely short half life which means your kick will be shorter, though more potent, as well. It's painful, but you have to consider that your use was your decision (no judgments) and that you may have to pay a short-lived price for it.
Withdrawls are difficult because they are painful so we seek out easier ways of getting through them with more prescriptions. Unfortunately, I can speak from an addicts perspective that being given something less potent will only tempt you to abuse it to achieve the euphoria you miss. Have the courage to do it cold turkey and don't commit yourself to an in-patient institution. The experience of being treated like a drug addict can sometimes add to the anxiety you will feel.
