Hey I was on Seroquel for quite some time and can tell you that it increases your chances of becoming lucid. I have been on and off Seroquel a few times now and the times I was on it I always had more LD's, and whenever I came off it I noticed a huge drop in LD frequency. It is considered a tranquilizer and not just an SSRI, you definitely get deep uninterrupted sleep with it that's for sure. I was sleeping for like 12 hrs a day on the stuff and had so many LD's. I wanted to get off it though because of the weight gain side effect. I had a lot of trouble coming off it because I became somewhat dependent on it to sleep. Besides those 2 problems its a great medication to be on and certainly helps with LD'ing.
