Agreed.
Moving forward, though - I would take as little Suboxone as possible. If you're only taking 4mg over a period of 2 doses, you shouldn't be that bad-off. I took 5 days off from work when I transitioned from Methadone (Much longer half-life) to Suboxone. A full 72 hours of morbid hell, followed by extremely small, but satisfying, doses of Sub totaling no more than a 1-1/4~ pill a day. By the end of three weeks I was done with it. Everyone's situation is different, and my doctor did advise against this method for the best chance of success. He did, however, advise for me to wait out the WD as long as possible (Even past 72hrs).
