insomnia
"I have had insomnia (specific diagnosis is sleep stage dysfunction) for over 4 years. I've been on Ambien, Ambien CR, Doxepin, Seroquel, Trazodone, Amitriptyline, Restoril, and now Belsomra. I have been following Belsomra and it's release for about 2 years now, and could not wait for it's approval! I'm so disappointed. Last night was my first night on the medication, and I had HORRIBLE nightmares! I laid awake for hours after I took it, and then fell asleep only to wake up periodically with these horrible nightmares. Ambien 10mg worked wonders for me for a while, but then lost its effectiveness as I became more tolerant to the dose. Plus, I had severe memory loss on Ambien, and I do not want to go back to that phase."
