6 days of no dosing when you have been going through the process of tapering and no withdrawal at all?
I'm not being funny but are you sure you've been taking methadone? Most people would be in unbearable writhing agony by day 3 at the latest, I know I would have been .
That sounds like an extremely, extremely rare situation. Not impossible I guess, but very implausible. If you have suddenly dropped from 85mg to 30mg you're surely going to be hit by a mass of withdrawal at some point soon as the methadone drains out of your system. I would wait a good few weeks for this to happen and deal with that first before even thinking about subs. If it doesn't happen I would be praising the miracle that has just happened, then you need to stop taking the methadone and wait until you are in a fair amount of withdrawal before you can even start taking the subs or you will be hit by a horrific amount of precipitated withdrawal.
As for the sharp bupe taper there's a thread somewhere specifically about just that but I don't have the link, pm neversickanymore they have it. I would suggest you're getting ahead of yourself here though, there's something very bizarre going on with regards to your methadone treatment.....six days of no juice without withdrawal is unheard of to me. Hopefully someone else can shed some light on what might be going on here, it sounds VERY strange though. Especially when you had already been tapering.
Being nervous is understandable, try to remain calm and don't rush things though otherwise you could end up getting yourself in a really nasty mess. There's lots of knowledgable people here, I'm sure someone will be able to chip in with some information to explain the situation. It's beyond the realms of my understanding though, I have to admit.
