I do like bupe, i think it's a very useful opioid, but I just had to switch to methadone. Financial reasons caused me to switch from a private prescription to a daily dosing clinic here in the States, and once-daily dosing of 16, and then 20mg, doesn't agree with my metabolism. With the private script I was able to split, 8mg morning and afternoon, and that would carry me, maybe add an extra 2 or 4mg if I felt I needed it. But dosing once a day, it seems no amount short of the max dosage would carry me the whole day, so I had to switch to the dark side, lol.
But yes, I like it, it definitely earns a spot in the medicine cabinet. I tell people sometimes that bupe is like the light beer of opioids, for those who enjoy opioids and functionality.
