Can't enter sleep paralysis.

After 2 years on the drug seroquel my one fear of coming off which was outweighed by the benefits of coming off was true. Seroquel was somehow causing me to be in prolonged stages and early onset of rem sleep. While my experience with seroquel was dominantly negative and reason I came off but being a insomniac seroquel was only thing that could make me fall asleep any time before 3-6am. I can't lucid dream anymore, well correction you never lose that ability when you achieved it. More like I can't sleep and therefore can't dream which obviously means I can't lucid dream. I sort of figured sleep paralysis was gonna be my go to thing now for lucid dreams, my body is always tired but my mind is always well not tired I know for sleep paralysis all you need is your body to fall asleep. Well I thought hey my body always gets more tired then my mind so sleep paralysis should be simple. Well that ended up not being true for what ever reason after I got off seroquel I just can't do it. I mean I should probably try more I'm pretty figidy and have a low attention span and I guess I didn't try as much as I ought to. It's just on seroquel I can lay down just for a bit and few minutes later I can't move and someone opens the door and talks to me I get dragged around the bed voices etc. you know regular sleep paralysis stuff. Obviously insomniacs must be able to deny sleep physics or something because this makes no sense at all. I'm tempted to get back on seroquel but it's not gonna happen the drugs to dangerous to just use for this. So I guess a good thing to ask for is sleep paralysis/lucid dreaming tips and techniques for insomniacs.
