Depression
"My doctor prescribed this to me for the depressive episodes (as part of my bipolar dx). 
At 0.5mg, that was sufficient to stop crying, but I was exhausted, mentally. Perhaps numb. Not sure if it was from the depression/crying or the medicine.
At 1mg, it knocks me out. 
I now use it mainly for insomnia, and no more than once a week.
Any more than 0.5mg at 11pm and I will not get up on time for work.
Because this is my own use, I confided in a friend (who had a stroke) and he confessed he had been doing the same thing until his MD stopped him. 
I believe insomnia may be a good use for this medicine IF USED CORRECTLY. I know it may have addictive potential. Monitor yourself."
