i have taken a sub around 12-14 hours after last oxy dose (overnight) and have not had any precipitated w/d's. NO idea if has anything to do with it or not, but i have an incredibly fast metabolism.
Also, on a side note...something i have thought about with this whole suboxone and precipitated w/d's (and i apologize in advance as my knowledge of the actual science/chemistry behind it is not great) :
my understanding that you will get precipitated w/d's if you take a sub too soon after another opiate because the bupe will strip the opiates off of the particular brain receptors (again, not sure of the correct terminology) and leave those receptors with nothing on it.
Assuming that i am correct so far, if that were to happen, what if you took another sub shortly thereafter? say, an hour or 2 later. If the first one strips all the opiates off of those receptors leaving nothing there...it would almost seem logical that if you were take a 2nd one, that THAT one would attach itself to those receptors just as if you had waited the proper amount of time between the last opiate intake and the suboxone.
I hope that makes sense....
