Doxylamine
"I took Doxylamine for the first time last night. I have suffered terribly from opioid withdrawal induced insomnia for a long period of time and to sleep I was given Seroquel, which did not help but left me completely "hangovered" in the mornings and had serious side effects. Instead, I tried the OTC Doxylamine and I have slept seven straight hours without nightmares and feel great and wide awake in the morning. I can not generalize after only one experience but would really like to recommend it."
