I had the same experience with tinnitus and visual snow, and unfortunately, they are still present. While I had one bad trip, I was okay after that one. However, after waking up from another trip, I simply wasn't the same. The depersonalization was the worst part - it left me in an awful state of mind. It's been so long now that I'm not even sure if it's still there or if it's become the new normal. In fact, I couldn't even tell you what normal feels like anymore.
For me, the few hours of fun weren't worth the amount of stress that followed. I got nothing out of it except some temporary entertainment.
I strongly believe that using LSD in therapy is malpractice. It is not right to give such a potent and mind-altering drug to people who are already dealing with mental health issues. I worry that in the future, we will see a rise in similar cases to mine, as LSD becomes more commonly used in therapy. And although I turned out OK and I can deal with the condition I am scared about how people who might already be suicidal deal with such a life altering event.
