"started on doxepin 100mg january 2017 due to debilitating gad and panic attacks. i was miserable. ten minutes after waking up, the panic attacks would start. i quit going out in public as much as possible. at night, i couldn&#039;t shut my mind off, which exasperated my insomnia. i was taking more xanax than prescribed to try to get through the day. i specifically asked my psych for this based on reviews. helped right away with sleep (with no next day grogginess for me), and after about a week, started putting the brakes on my anxiety. slowly noticed i was getting parts of my life back. it served its purpose and pretty darn well, but in ten months i gained 30lbs and kept gaining.  due to the ongoing weight gain i switched to gabapentin instead."
