it can take up to 2+ weeks for your body to completely adjust to the Sub. The adjustment involves how
the bupe fills the receptors versus how
your DOC did. You may feel a little "weird" during that time. That does NOT mean you would need more Sub. Even if you feel slight w/d symptoms, that's normal, that's the body adjusting. It should be VERY tolerable.
After the stabilization period, then your doc will probably (hopefully) begin discussing the reduction process.
