So I did not have specially bad experiences, but on long terms I wouldnt want to use them. So I had for 6 weeks some medics that were a combined antidepressant and sleep medicine. So it really helped me to get a normal sleep rhythm again. Anyway, as long as I took them I simply "faded out from reality into my own thoughts" all the time. I wasnt even able to order a burger menu at burger king, without fading out two times. So I ordered and when the waiter didnt listen, as usual, and had to ask something again 5 seconds afterwards, I already was again in my own thoughts and so on. When driving through city traffic, I always faded away into my thoughts, when I had a red light. One time I stood in first position, faded away, got back, saw that I had green, wanted to start and saw in the last seconds that somehow a big motorcyle had passed me, and stood before me now. So it was loud and it must have passed me slowly, but I didnt get it. This was really making me afraid. So for 6 weeks, to get back to sleeping again, its ok, but for a longer time, I were afraid of traffic accidents and so on.
