I am in the same situation because I also take sleep aids. So far I’ve been sleeping but I’m not sure if it’s because I’m sticking with my sleep window or the sleep aids. I’m too scared to go without it. But so far I’ve been doing the things I enjoy during my sleep window like reading and watching youtube on my phone. My fear of nighttime wakefulness is getting better. So I am hoping that someday I will go without sleep aids.
