OP, you said you had a stash of something 100 x 10mg....you didnt say what it was?? Personally, I would leave the subs out of the equation and just deal with the WDs, especially considering whatever it is you have from your secret doctor. Or you could go with the really, tiny dose and let it work its way out..
Shwiftee, though it sounds good in theory, when you have control issues like so many of us do, it might have been pretty difficult to use those 3 bags to taper down on..personally I couldnt have done it and using them would probably have led to more bags.
To whoever posted about not having withdrawals unless you have at least 3 days of continuous use, this might not always hold true and the same for someone that has a long history of opiate/opioid addiction.
Good luck OP, it really did take a lot of will power to flush those bags. It is a show of strength which mean you should draw on that strength and maybe it will help you to not go down that road of 2 or 3 months of use again.
