sedation
"I've been diagnosed with MDD and anxiety. I've always had trouble sleeping so my psychiatrist gave me hydrozyzine 25mg at first and it wasn't doing anything so she upped it to 50mg which still isn't working. My prescription is always being filled so I still have a bottle or two of 25mg and one of 50mg. I'm still taking it and trying to sleep but it's really difficult. Even when I actually feel dead tired, I still can't sleep. I usually end up having to wait till my body gives out to get any sleep. I can't go to psychiatrist because I'm currently not a student so I'm not sure what to do. 
If this medicine works for you, congrats and I can't deny that I'm jealous."
