I dunno, the methadone withdrawals are too burned in my mind to want to prolong this.
I was sober most of 2018, all of 2017, and 2014-16, and once I can just get to a month or two, I'm generally okay on lowest therapeautic dose of Welbutrin and/or Lexapro, plus 100mg of trazodone for sleep.
I see your point, and I do like opiates, too much to want to keep fucking with them if I can avoid it.
I'd rather reserve them for those inevitable 'thousand mortal shocks that life is heir to' like when I slipped a disc renovating my mother's lawn last year, and needed a stretcher to get back out of the house... Some things are only easable by a low tolerance and IV Dilaudid.
