insomnia
"Worse drug ever.  Terrible groggy feeling next day. I usually take ambien 10 mg however since manufacturers have changed 2 North Star desperately I was seeking something else unfortunately this is definitely not the answer the next day you will feel like you've been run over by a train, depressed and unable to accomplish anything!!! Terrible stuff,  warning do not resort to this garbage. ..it is just horrible.  These are going straight in the trash, I'm going back to ambien tonite,  at least w northstar , when u finally do go to sleep,  you wake up refreshed!!!!!"
