I'm currently addicted to benzodiazepines as well as opiates. My benzo habit isn't too bad, though lately I've been getting out of control with them, which is why it's been nearly 60 hours without a dose (clonazepam-long half life-usually takes me about 72 hours to really feel fucked up, I currently feel just incredibly twitchy), and I also take Methadone, 50mg/day and have been (since the end of September :-/) been shooting dope daily on top of it, which btw, is a very dumb thing to do, especially on a maintenance dose that is on the lower side of the spectrum..basically my methadone works as well as shooting five bags in the morning would-I feel good, no withdrawals for about 7-9 hours and then I start to feel uncomfortable again.
It's a really shitty situation I've gotten into, and now its gotten to the point where I need a bag in the morning to ensure I'll even get to the clinic..it's weird I guess, but my clinic is an hour away, sometimes more depending on the public transportation's efficacy, and I absolutely dread that trip unless I already have something in my system to get me there. There's a misconception that methadone outrageously potent, and that using Heroin on top of it would be like taking a T3 for someone who normally shoots Dilaudid, and its just not true. Methadone potent, but its not 'fentanyl style' strong. If someone is on methadone but under the blocking dose, shooting a bag or a 'point' would still effect you. And shooting two bags would probably make someone nod out even more because of the methadone.
Not to drag out this post as well as this topic, but I always hear people say that if you want to get high on heroin while on MMT, one would need to skip a day, or fix before going to the clinic. I find its the exact opposite.when I fix in the morning, I just don't feel sick...beyond the rush, the dope doesn't produce any more euphoric effects because its filling up the receptors (or some of them) that the methadone usually takes care of. If I do the same amount of dope about eight hours since taking my methadone, it hits me pretty hard (this all of course depends on the heroin's potency). In the end though, its not worth fucking up my tolerance for. It's frustrating too, because I know that probably after five days I would almost fully readjust to my methadone dose, but five days only seems like a small amount of time when you're not fiending.
