Thank you for your question and welcome to AnxietyConnection.com.   Trazodone is a tetracyclic antidepressant and can have sedative effects as well. As far as whether these medictions work together, I am not a medical professional and would not be able to answer this. Your doctor or pharmacist would be better able to answer this question.   As far as whether your daughter should return the watch, that would be between you and your daughter. I understand there is sentiment attached to the watch, however, it was a gift. Is it possible you and your daughter will begin talking again in the future?   Eileen
