I'm on 55mg of methadone a day, it's basically what I need to get by without any sort of buzz. Once I hit 55mg I found I experienced 0 withdrawal and decided to just maintain my dose at that cuz I'd eventually have to taper down so I figure the lower amount I can get by on the better. Anyways, I wouldn't mind catching a buzz and don't want to use so I was wondering if anyone knows of any potentiators that I can use to potentiate my methadone dose? I've used grapefruit juice and naproxen before for other opiates (oxycodone when taken orally), do these 2 things work for potentiating methadone? Lastly, what other things will potentiate methadone?
