insomnia
"For everyone who has experienced negative results from taking Belsomra  & from a well-experienced insomniac, I was advised by a very knowledgable pharmacist that in order for Belsomra to work properly & effectively (after having taken Ambien for many years), I was to stop taking Ambien & let it completely wash out of my system for 3-4 days before starting Belsomra.  She stated, that this medication, unlike Ambien, is not supposed to assist you in falling asleep, as so much as it works to help you stay asleep, however, it won't work as it should, if I don't have a break between medications. After reading all of the comments about Belsomra not working for so many people, I'm definitely intend on following the Pharmacists instructions to the letter."
