hello user , thanks for contacting health care magic for your health related query . i understand your concern. you have however not elaborated that why do you feel that you are sleepwalking - have anyone witnessed so ? or its that you are not having a refreshening sleep - since you are taking escitalopram , i presume some ongoing or past psychological distress associated , also if you are having weight issues and hormonal disturbances. cumulatively all these factors can independently and/or jointly can result in sleep related disorders. you should consult a psychiatrist for detailed evaluation and management - also you should practice sleep hygeine measures , which you will easily find on internet search . Take care
