Your fine right now hun.WHat they forgot to mention, is that even though you took 4mg, only 20-30% actually gets into your system.This is becuase the bio-availability if suboxone is so horrible, that, unless your injecting it, you get only a fraction of the dose.Thus, if you took 4 yesterday, 1-1.5mg actually ended up in your blood stream.4mg the day before means the exact same thing.So by yesterday, your dose from the day before had reduced to about halg a milligram, and by today, yesterdays dose is also around half a milligram. All in all, there is less than a milligram in your sytem, and, depending on your metabolism and tecnique, there may be nothing.So your fine hu.Actually, you would've been okay yesterday.No offense to the people who replied to you, but they we're misguided.I myself have now moved on to IV'ing Suboxone, and if I am forced to do Subbies, in my vein is the only way that's worth it, as 1mg injected makes me feel fine, while it takes half a pill under tongue. But for future reference, it's ok to take other opiates after Suboxone, as long as there is less than 1mg in your sytem, and less than half to be safe, with a minimum wait of a few hours if injecting, and 12 or more sublingually, depending on dose.To figure out how much is in your system, refer to bioavailability charts, they are all over the net, just make sure to reference the info.Also, IT DOES NOT take 72 hours to eliminate 75% of the "active" dose, otherwise one injection would have you geeking for days LOL!!! I don't know where the math came from, perhaps he was thinking about actual clearance?in any case, it never takes more than a day to get full effects from other opiates, unless extremely high doses are used, though again, you would need to inject for that much to get into the system.
