"i have been taking 40mg latuda for about 2 weeks.  no side effects and it does not make me drowsy. i take it with dinner and i&#039;m fine until i go to bed at 9pm.  i fall asleep fine and wake up refreshed. i feel so much better - i have been able to stop taking depakote and ambien. now, i&#039;d like to get off the lithium. i still have anxiety and irritability but now i can get ahold of myself and see reason and calm down on my own. i would highly recommend. it is expensive though."
