insomnia
"Weird!  A bizarre full body and brain sensation. I went I and and out of bouts of sleep the first times I used it. While the sensation wasn't pleasant  (I felt sort of high in a not terribly comfortable way) I did get a decent total number of hour of sleep. Still it was weird enough that I didn't want to repeat and only did so again after intervals of several weeks.  In total I took it maybe 4 times.  

Took again tonight and again had a long, trippy and not very pleasant initial period then only slept about 5 hours and woke up feeling quite badly. 

Sorry, Belsomra, but you are going into the trash."
