"this medication knocked me out every night and so it was great to catch up on years of sleep debt.  overall, a very positive experience.  however, like other users, i slowly gained 10-20 pounds over the course of taking doxepin. i stopped taking it in the last couple of months, and suddenly, my appetite significantly decreased and weight just started dropping off. i had no idea that the medication caused this increased appetite/weight gain. honestly i thought i was just growing older and my metabolism was changing. i&#039;m glad i took this medication for insomnia, and also that the side effect of weight gain faded away as soon as i stopped taking it. overall, the value of the sleep i gained far outweighed the con of the weight i gained."
