Hi, I also took trazadone in the past in a high dose...it did the same thing. It ended up giving me horrible nightmares and I still ended up feeling like I hadn't slept. I will go 3 or more days without sleep and I feel like I am going crazy and on raw nerve. You definately need sleep. Have you had a sleep study done to see if there is something happening? You might want to ask your doctor about that.
