I guess that my reasoning comes from the effect of methadone on my addictive side. I have never felt the constant urge to take more in order to feel better or higher. I feel a reasonable pain relief (not quite as much as with other opiates) but I can get by with only a couple of dones per 12-18hrs compared to a constant feeling of 'want' from the others. You are correct about the dangerous possibilities of over using the methadone, however, in my experience I don't feel any difference from 3 pills to 8 pills at a time. I guess that as long as you are on a couple, you don't need any more where as with oxy's and Fentanyl, I constantly found myself chasing a dragon. I suppose it is a personal choice that is difficult to make. For me, it was a choice that yes, kept me from feeling a euphoria and having abilities similar to those before my injury. I did also experience almost too good of a pain kill from the others. I know that sounds ridiculous but I was capable of working my body in ways that because of my injury, I should never be able to. I suffered re-injury because of it. Since the change to Methadone, I have according to my family and friends, been much more 'down to earth' and not so 'crazy out there' . I also was running out of my prescribed meds every month and it was getting worse and worse to the point that my Pain management doctor almost cut me off completely due to DEA regulations. I found myself wanting the Fentanyl so bad that I took 4 patches last super bowl sunday along with my prescribed dose of Percoset and benzos. I was of course loopy for some time and when I came to finally about 24 hours later I learned that my good friend just died, OD from fentanyl patches. I am obviously biased but I feel that it is much easier to control an addiction to methadone than to almost any other opiate.
