Insomnia
"OMG! I tried Belsomra for the first time after several years of taken ambien. My doctor told me to try it so I could get off the ambien. Well the first 10 minutes after taken, it I got a horrible and quick pain on the left side of my brain..it was so bad I let out a loud OUCH!  I did not get sleep was up all night and the next day  I did not have to work. My behavior was like someone with narcolepsy up and down all day.  Now I don&#039;t know if this has anything to do with it but I hadn&#039;t had a cold or cold like symptoms in 10 yrs and after taken Belsomra for 1 day I got sick.  I will never take Belsomra again.  I will go back to ambien.  I contacted the FDA and told them about my side affects."
