DSIP really works well for me, but I need to use it every evening. I don't have nightmares anymore, but I do dream now. Before using DSIP, I didn't sleep deeply enough to dream. Also, when I wake up at 3 am, which I always used to do, I can now get back to sleep. It's been a lifesaver for me. And as mentioned before, less is more. I only use 100 mcg, and it still works effectively.
