"i&#039;ve had insomnia for years and used only natural remedies to cope.  eventually none of the things  worked, so i went to a sleep disorder clinic.  the doctor gave me free samples of belsomra 10, 15 &amp; 20 mg.  i started by cutting all the pills in half and taking only 5 mg.- that worked for a couple of nights only.  i then had to up the dose to 7.5 mg (by combining the cut pills).  after a few nights of each dosage, i have to up the dose.  i don&#039;t use belsomra every night because it doesn&#039;t work consistently.  i still mix up the nights with a melatonin spray.  although i get a decent sleep with the belsomra (when it works), the next day i have a heavy head, like brain fog.  i won&#039;t be paying for this when my free samples run out."
