Methadone and opiate tolerance

[Opiatelover710]

So Im a experienced opiate taker never taken methadone before but I can take high doses of oxys fentanyl and other opiates. I was wondering how many mgs of methadone should I take to get High recreationaly of course. I don?t go through withdrawals just looking to have a good few hours high from the methadone. I know that methadone has a really long half life. I don?t know the equivalent of the methadone to morphine or oxymg. So any help would be much appreciated
