Last month I tried Dxm three times (300/150/450 mg) and they were great .. But in the last experience of 450 mg something strange happened, I became very emotional and I was remembering some bad memories and some mistakes I made in the last years that affected my life negatively. And realizing how these years passed so fast . The most important thing is that after this experience, a few days later, I had a somewhat disturbing feeling. I don’t know if I can call it depression or not, but it is a feeling of distress and sadness and that nothing in life has a meaning, knowing that I have never felt this before, although I have done a lot of drugs!! So what do you call this thing?
