insomnia
"After heart surgery in 2014 I went from having normal sleep to insomnia and vivid dreams. After 10 months I medications and dietary supplements.  I have recently tried Lunesta and I have found that I only get 2-3 hours sleep on Lunesta and I do have that taste in my mouth went to a doctor. We have been trying different the next day. Ambien works great but it is a wicked medication to take for very long.  You build up a tolerance to it and the withdrawals, for me, are 2 nights without any sleep.  My doctor and I are still working on a treatment and a cure. Medical Marijuana is out of the question for me but has been recommended by my Colorado relatives but I'm not going there."
