i also think as you do opiates...more and more...they are in your system...so if you are doing 120mg a day there way still be 30 mg floating around in you from the previous night.
it's a dangerous game...that's why you should stop now.
the pain of quitting is much better than the end result of staying on them...death.
That is a question that can't be answered. Everyone has a different tolerance towards opiates. For some it could take as little as 40mg I would guess. For others it could be quite a bit more. If you are really wanting to get off of them for good, you found a great forum. There are some wonderful and amazing people on here that will not judge, just give you advice and encouragement.
Since you are tapering the first thing I would do is start taking them orally. Snorting can be so much more addicting. You never know when you could actually od so you should stop right away. Please stick around this forum and post your story. We will help you beat your addiction. Life is so much better off the pills.
Please stick around. You will get so much support!!
Best of luck to you!
