"my ob recommended this for my insomnia/racing thoughts at night in pregnancy. took 25 mg and was out w/in 30 minutes and tired the next day. cut down to 1/2 a pill and was much better. haven&#039;t gotten a full nights sleep in 6 months and was losing my mind, it completely fixed that. i will say that if i don&#039;t drink lots of water with it i get terrible headaches but as long as i stay hydrated and give myself 8 hours to sleep i am ready and wake up right away with my alarm in the best mood i&#039;ve had since the pregnancy started."
