"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."
