I'm currrently taking depression medication due to chronic back pain, my reason for taking the medication I was having problems sleeping, waking up in the midddle of the night and sometimes taking hours for me to go back asleep. I've been taking amitriptyline for almost 3months now and it has helped some but sometimes when I wake up in the morning and try to go back to sleep I still have a hard time. I also have exeperienced side effects of the medicine I have gain a few pounds, I notice my breast have enlarged, and some decrease of libido. Should I continue taking the medication or have my doctor prescribe me another medication.
