anxiety
"At first I was on 25mg as needed and took it about an hour or so before bed to help me "turn off" my mind and help me sleep a bit.  The next morning 10+ hours after taking the pill, I was a walking zombie until well into the afternoon.  My dosage was lowered to 10mg and although I didn't have the major day after drowsiness it still helped me sleep.  I took it during the day and it felt like I took several Benadryl's and I was unable to function for the afternoon because I was so drowsy.  Good thing I was at home when I took it.  Unfortunately, although it did help me sleep, it didn't do much to calm my anxiety.  I took it at the start of an anxiety attack and 40 minutes into it I was still having symptoms."
