I'm thinking I'm both not pre-disposed to like opioids and also I haven't tried a strong enough opioid. But I'm curious what these drugs are like for others.

I did oxycontin once on shrooms. It only made the shrooms more enjoyable. Didn't think about it ever again.

I took large amounts of Tylenol 3 (codeine) multiple times and felt a bit warm and relaxed, but that was about it. Could take it or leave it. Didn't really "do" anything for me.

I took tramadol for a week straight. Anything more than one pill makes me violently nauseous when I stand. The best I've gotten from it is a "warm" feeling, but it was something I could take or leave. Tramadol actually made me highly anxious, unable to fall asleep, and hypersensitive to any sensation of touch on my body. It was unpleasant overall.

Is this standard for these forms of opioids or am I just not pre-disposed?
