sammy, you do realize that all those great opiate effects will eventually diminish, and no matter how much pst or opana you take, you still won't be feeling like that again, right?
you said you've been doing opiates every day for a year - i'd consider that honeymoon phase still. i know you think 20mg opana is a lot, and i guess it is, but you can get way, wayyy more carried away, trust me. tolerance really only goes up in your current state of mind. once you've been hooked for several years you will likely regret your thought process now.
the pst isn't going to be as fun as railing OM, not by a long shot. its way more sedating & subtle. and you can't just 'drink a ton' because there is a ceiling effect on codeine, and i think on the morphine as well.
i think you're mistaken about the price as well but you can figure out why that may be on your own.
