Thanks. I have improved and now I don't experience flashbacks anymore. In one of my trips I lived the same situation except for the fact that it was all in my head (weird drug isn't it ). I thought my friends had called the police and I saw police lights and sounds and lived the whole scene because basically I had dosed too high and couldn't almost see reality anymore. Anyway through these years I have been suffering also from cyclothymic disorder and I highly suspect it was caused by the drugs (they turned cyclothymic temperament into cyclothymic disorder). Let's see how it goes from now. This disorder isn't always chronic (it's different from bipolar disorder). Since all of my symptoms started when I was abusing drugs, I suspect that they were stressors for my predisposition to cyclothymic disorder. In fact since I quit everything (five months ago) I only had two mood episodes and both were less intense than the ones I used to have and lasted only a couple days. I hope I won't experience symptoms anymore so I will be left only with ADHD that for me is way more manageable.
