DH had chemo for 2 years and in his case he would often have different drugs different days. Mostly it is IV but sometimes tablets and injections. He pretty much felt blah most of the time. Some drugs would make him vomit straight away, some would make him constipated, sometimes he would feel ok.IT depends on what cancer the chemo is for too as to how it effects people. DH used to get insomnia from some drugs and really sensitive skin. He didn't really avoid any foods except when he jsut couldn't stomach them. He limited his alcohol also because he jsut couldn't handle it. He wasn't allowed to do any gardening. If anyone was sick with ANYTHING also they had to stay away.
Again I stress it really effects ppl differently. Maybe have a chat to the family and see how she is coping?
