<s>[INST] hello doctor, i tried to convince myself many a times, but failed. my father behaves ia an unnatural way. he saya himself to be god. he doesnt sleep at night and doesnt let other sleep. he speaks a lot of useless things. he was previously dependent on intoxication but now after the doctor recommendation we have forcibly stopped everything. is it due to the stopping of intoxication or what  and why he becomes so irritated. we are living in orissa and from a middle class family. kindly help [/INST] Hi dear, what ever you describe about him suggest that he might have bipolar mood disorder, and it may be due to the substance which he took, or it may have individual entity. For proper diagnosis we need detail history and mental status examination of him. You need to consult psychiatrist. There are many medications which controls his behavior and symptoms also like mood stabilizer sodium valproate, lithium, carbamazepin, etc. also anti-psychotic medication like olanzapine helpful. Thank you </s>
