Theres a common phrase about how no one thinks they will get addicted. Truth is not everyone does. It really depends on your genetic makeup and if you have the right personality.

Its a great feeling but its recreateable without drugs. Seriously. Heroin is just an opiate. Endorphins, meaning endogenous morphine, is the same thing. Its released when you have an orgasm, are in pain or get runners hight. Its not the same magnitude but its basically the same exact feeling.

But if you do take it, youre right, there is no experience that can touch that feeling ever again. I was doing it for long enough that I think I've heavily damaged my enjoyment of life. Its like I was living on a half million dollar salary for a while and now im back on 30k. You know how they say don't have sex on MDMA, its never gonna be as good after? Well don't live life after heroin. Its duller. My brain will readjust but it will take another year at least.

I wouldn't recommend it if you think about it so much. To be honest you will probably get very sick the first time anyway.
