I don’t know if you are still checking this site, but I just wanted to add that I recovered sleep after about 18-24 months off of Propecia. It’s still not perfect, but neither is my skin, my desensitized gentalia, my dry eyes, ringing ears, and poor short-term memory… still have all of this after 5 years.
Whatever is wrong, I’m certain that my body does not produce the same mixture or proportion of hormones in either my prostate, dermis, or both–and maybe other areas. My sleep and anxiety are not nearly as bad as they were 5 years ago. Yet, it doesn’t take to much stress to give me high anxiety–which would probably indicate some hormonal problem that persists.
Make sure your eyes are moisturized (salt water/saline solution) and try to spend less time near lighting that bothers you (for me, flourescent light bulbs cause pain).
