I started using ketamine early 2023 casually on weekends. A gram would last me a couple of weeks with friends. But I started to ramp up my usage throughout 8 or 9 months until there was a week or two I was using about a gram a day for just myself. I started to get cramps so I stopped using for about 10 months. Over the past two months I started using again and quickly starting taking about .5-1g a day. I started noticing I’ve been peeing more frequently the last couple weeks but yesterday I woke up with really bad cramps and what felt like stinging in my bladder. Have I done irreversible damage? What are next steps? Anybody have any advice? I'm kinda worried atm
