insomnia
"Worked well at first, but then stopped working, I have to take 5mg melatonin every night, 6mg prazosin (for PTSD nightmares), and 50mg of benadryl now for it to promote sleep onset successfully. I feel my body wakes up around 6am, (depending on the time I take it mostly). I don't know if it's my body becoming completely dependent on Lunesta to sleep, or taking my Prazosin lasting only about 6 hours causes my blood pressure to rise when it wears off making me wake up, or if I have back issues making me awake after it wears off. I think since I have delayed sleep phase disorder, my body has become too accustomed to the medicine to remain asleep due to the long duration of action, in comparison to the short duration of action of ambien."
