"i suffer from obsessive thoughts, anxiety, depression and poor sleep. mirta has a very powerful effect on me. i break a 15mg tablet in half and half again  to about 4 mg and it still knocks me out all night with a solid sleep. the next day i&#039;m only about 60% alert until the evening when i become fully alert. it takes away sexual drive and sometimes causes restlessness before sleep. however it does reduce anxiety well enough to sleep. i have been using it when i need it."
