I have two 15mg ER Morphine pills and two 5mg Oxy pills. For somebody with no tolerance whatsoever, how should I dose?

Not sure if measurements have anything to do with dosage but I’m 6’1 and 165lbs.

I will take any advise as long as it’s not “you’re treading a dangerous path” or something of the sorts, I know. I’m also not going to IV but I’ve thought about plugging.

Should I take it all together? Any potentiators/synergizers to make them last longer or feel better? I want the best out of these pills because I won’t be getting real pharma opi pills like this in a while, and from what I went through to get these, I don’t want to waste the pills either.

I want to experience a nod but I’m not sure if the dose for that would make me too sick or not.

I’ve considered benadryl/plugging, just want to get the doses right and hear others’ experiences. :)
