"took this medicine july 2015- early december 2015 for insomnia, with the dosage at 25 mg, and this stuff really knocked me out for 9 hours straight every night. however, it left groggy until the evening next day, even with caffiene. afterwards, i stupidly decided to see if i could go without trazadone for sleep and i slept really badly for the next month, until i started the trazadone back up. this time, the trazadone worked for about 3 days before it stopped working, even with me bumping up the dosage being 100mg. sure it maybe can help with sleep, just don&#039;t develop a reliance on them."
