I dont understand all the fuss about Heroin?

I mean I always heard when younger how dangerous is and that once you take it your done. And of course I believed it and was terrified if I heard someone is on heroin. It sounded almost like saying this guy is a dead man walking. Well that was until I turned 20 and I had a little bit of Heroin at home and tried it orally...And I did it 2 more times after that occasion...and my experience it is hugely overrated drug, I mean I never ever could imagine....Its like really strong weed expect it makes you nauseous and honestly I could never be addicted to this drug its just not that good. Its like being tired as *** or lets say you feel like you havent slept for 30hours. Anyway I think people are different and they react differently to things. So maybe I am just an exception but I really cant believe it destroys lives. I mean how can someone crave so much for the feeling that isn't even that good. And steal rob and so forth I really dont get it. ITS NOT THAT GOOD. There are things in everyday life that are much more interesting to me then heroin. Well thats just my opinion and experience.
