80mg knocked me down on my *** (butt). I slept pretty much the entire day after taking it, but it took me a lot longer to fall asleep than usual.

40mg helped me with sleep and I had no side effects.

60mg, which is what my pdoc currently has me taking has increased my agitation, makes it harder to fall asleep, and I sleep less as well...so I'm unhappy with it, but I'll deal with it for a few more days until I see her again and we can talk about it.
