"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 &quot;hangovered&quot; 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."
