Similar to the above - never lasted 24 hours for me and never felt truly comfortable at any dose but it's better than clucking. Bupe pisses from a great height over 'done for maintenance/withdrawal, in my experience but others have better luck with 'done. Withdrawal from it is an absolute bitch though and I also found it made me deeply depressed and kept me addicted to opi's for many years more than I needed to be. I was on it on and off (mostly on) for around 10 years at various doses up to around 100ml for a pretty heavy heroin habit.
I don't understand why so many people here think that MMT isn't as 'good' as suboxone/subutex (buprenorphine.) In my opinion, bupe didn't do shit for my cravings and I ended up shooting the Subutex tablets; not very great for maintenance. Sure, bupe is better than methadone for detox, but for maintenance, methadone is much better than bupe especially in the craving control dept.
Most people think that they can control their addiction without having to use ORT (opioid replacement therapy.) This stereotypical 'arrogance' of the addict makes the majority of addicts 'hate' methadone; because methadone is a LONG-TERM opioid replacement therapy and isn't made necessarily for short term like Subutex/Suboxone is/can be used for.
Also, I notice that the majority of addicts who complain about methadone/MMT got on methadone not realizing that it is a long-term therapy and weren't ready to make the commitment that MMT requires before getting on it. These people usually don't understand the dynamics of addiction and think that they won't relapse and will be perfectly fine if they got off of methadone... which is 100% wrong. Instead of obsessing over controlling and treating their addiction, the majority of these people 'dissatisfied' with methadone obsess over trying to taper off/get off of methadone, thereby making their addiction treatment useless.
The fact is, the majority of times when the addict is off of ORT, they relapse. But the addict keeps thinking that it's 'better' for some weird reason to not take any opioids and battle their addiction 'sober', even if it means many relapses and many withdrawals, instead of taking methadone. The mindset of addicts are strange... myself included, lol.
