My son also complained of this,every thing tasting of chemical or metal,and he sniffed everything
Thanks for your reply flindy, has your son stopped taking this and has his sense of smell come back??
He stopped taking it a year or so ago,because of the depression,he no longer complains of the taste of things,but every once in a while i catch him smelling things,it was like ocd before but much much better now,his friends laugh at him at point it out to him when he sniffs things,but in a nice way.I think this has help curb that behaviour.
depression reply sense of smell windex loss of smell loss of smell and taste
