I've been falling asleep pretty well - but after a few hours our male cat wakes me up meowing. I think he gets anxiety in the night when it's dark and all is quiet.

He's usually upset for about an hour. He has kitty calm down drops but he hates them so I try not to give them unless he's acting outrageous.

So - my sleep is good for a few hours, then I'm up for a few hours, then I doze for a few hours. No nightmares since I started the prazosin though.
