Hi T Donnelly and anyone else who is reading this.
I am so sorry you have been feeling so under the weather from your Herceptin treatment. Oncologists and/or chemo nurses might be able to suggest medicine for that. There might be a dietician, nutritionist or natropathic physician in your area who can help you plan a menu that will not make you sick if you decide to try some more Herceptin in the future. Maybe your doc can refer you to somebody for that kind of help. There is a list of Herceptin side effects at
http://www.herceptin.com. There might be some information about your side effects there. Everyone's body is different, so not everyone will experience the same side effects from medicines. Hang in there.
