It isn't fair, but that's what happens when you use pain meds. Our bodies have a tolerance built up. When you quit for awhile, it will work better for only a bit, then you're right back up to where you were before.
girl i am sorry you were sooooo sick . I hope you do get to the point you want to quit . You have consumed so much of the drug that is why your tolerance is soooo high .Stick around ......
