The fact that you've been on Methadone for 20 years does obviously not work in your favor, but you are also on a relatively low dose. Patients who attend Methadone clinics can go as high as 240mg. I've seen it, so don't call bullshit. I do apologize because I haven't read the entirety of these posts, but I do have a recommendation for slow titration. First of all, I really think the only way to accurately dose at low intervals is by making a volumetric solution with your pills. How I would go about it, would be a 0.5mg decrease every 3 days or so. Why rush it if you don't have to is the motto.
What you should do, is take a measuring cup, crush your methadone pills. Make a solution with say 10ml of water. Mix the water with your crushed Methadone pills. This way, you know that every half milliliter is equal to a half milligram of Methadone. You can go about dosing the small increments this way until you are done. Alternatively, an oral syringe with a similar volume can be used.
