Yea I started to lose my vision too many times from it, which is when your muscles are having a seizure, including your eyes , it's near death, a little ways to go, but not a lot. Its typically from excessive IV use. My buddy used to get the kilos with the cartel symbol on them. Smelled like ether to high heaven, we would all take a line and immediately puke out the car window. So glad I quit that shit, I did ding up my heart though, it's not close to 100% anymore, but it is what it is. I have crohns disease anyways so it's not like I'm gonna live a long healthy life. These days I smoke my weed, maybe trip a little and hang with the family. I got old and boring
but I like it. I rode a wild ride for a long long time before I got off of it.
