"my psychiatrist recommended that i try 5mg of melatonin instead of other otc sleep aids. i have anxiety disorder and have trouble not worrying about intruders at night. i took this 30 minutes before bed time and i felt extremely tired within an hour. that was nice. i woke up an hour later from i&#039;m not sure what. easy to go back to sleep. then a total of 3 hours later, i woke up gasping for air. from a nightmare a presume, although i couldn&#039;t remember the nightmare. i then woke up around 5am from my neighbors in my apartment building. i felt alert but made it back to sleep. i then was not able to wake up the rest of the morning. i couldn&#039;t get up to go to work and i still feel tired at noon the next day. wondering how to move forward."
