Hi there, Needtotalk.  Sorry your wife is havign a rough time.  I have not had chemotherapy but there are loads of people here who had.  I would suggest that you talk to the doctors again;  there may be some reason why this sickness has to be tolerated but you and your wife need to be told the reasons for this.  If they cannot give your wife an alternative they need to say why.  Best wishes.  Annie
