anxiety
"It definitely calmed my anxiety but left me drowsy.  I took 25mg once a day for two weeks and was able to function somewhat normally despite the fatigue factor. After two weeks, for some reason, it began making me so tired that I was unable to function during the day. I tried halving and even quartering the amount, but it still left me unable to stay awake during the day.  When I was awake, I was lethargic and depressed."
