yeah, heroin is an incredible drug once you finally get the right dose and route of administration. it is, imo, hands-down the best drug out there. that is both good and bad.
if you are not addicted to opiates already, and you try heroin once, it's not like you won't be able to stop. even as much as i love it, i don't do it all of the time.
a word of caution, though; if you are looking to avoid something in your life (feelings, problems, whatever), heroin can quickly and easily become that escape hatch. once it does, and you become psychologically hooked, it's not long before the physical addiction takes over.
moderation is the key. that's sometimes easier said than done. if you are someone who isn't already an addict, and if you don't have an addictive personality, then you should be fine. otherwise, if you haven't tried it, i wouldn't recommend it. at least not now.
for me, i didn't try heroin until i had other things in order. yes, i was already addicted to opioids/opiates (started with back pain, and grew recreationally from there). But, not until my company turned into a multi-million dollar machine, I had hired the right managers, my relationships were fiigured out, etc., did I actually IV heroin. I'm glad I waited. It was worth it.
