insomnia
"It works perfect for me to go to sleep. I only took half of the the tab. I  sleept the whole night, for 10 hours, but I had a hard time trying to wake up!! I felt dizzy and with Migraine. I read everything about side effects, so I realized that I can't take this substance because I'm taking Eutirox because I have been diagnosed with HipoTyroidism. It works but its not good for me."
