One thing of note that I would like to chime in with is that receiving methadone as a once daily maintenance drug is not the same as taking it multiple times per day as an analgesic. Methadone can keep an opioid-dependent individual free of withdrawal for 24 hours, but the analgesic effects are actually more short lived.
This is why I do not understand how people are sent to a methadone clinic to deal with their chronic pain. Considering what I've read, heard and experienced a maintenance regime doesn't really kill pain at all once habituated.
Also, my knowledge is limited when it comes to chronic pain, as I'm a recreational user, but I don't see the reasoning behind all of those different opioids, especially the hydrocodone. I'm not saying it's wrong or anything, it just seems odd that you would be prescribed the strong opioids and then have hydrocodone thrown into the mix. Could you explain the reasoning behind it?
