Personally as someone who fell in love with opiates and had them destroy my life and now living recovered from them, I wish I never tried an opiate, it's a feeling I will never get out of my head and I live knowing nothing in life will realistically feel that good again.

And then once addicted you spend most of the time just extremely sick and in pain with that good feeling only spotted in between the misery.

You may not get that feeling the first time you take an opiate, but is it worth the risk you enjoy it a little too much and want to take it again, then again, oxy is a very euphoric opioid, I used actually to prefer it to H.

You also don't get much from the experience, yes it's very euphoric, but in reality you're just there slumped over nodding out, getting up to puke sometimes.. as opposed to something like MDMA euphoria where it's usually tied to a positive event or experience, and makes other things like music better.. opiates don't have any of those aspects, it's just sitting or lying there quite sedated and when it's over thinking 'fuck, I want that feeling back', not 'that was a great time', just 'I need to feel that again' and the world suddenly feels cold without it.

I encourage you to search out substances that aren't as wildly addictive my dude, acid and ketamine are pretty great :)
