my sister has been admitted into a phsyciatric ward and has been behaving extremely out of character. Mega highs then lows and not making any sense. very violent and she is by nature a quite, placid, loving girl. She is coming out with random things that have no relevance to what we are talking about. She is on 90mg Cymbalta-anti-depressant and has been for some time but doc prescribed her the dual Champix and her second week into them and she is under constant care now in secure psyciatric ward!! Please tell me if this is a side effect that will pass and how long do you think that she will be back to the happy, loving girl we know and want back?
