Hi sickgirl, What a horrible time for you. I took Herceptin from the beginning with chemo and then continued for twelve months. I didn't have any side effects from Herceptin, but I got a lot of lingering side effects from chemo. As I was on 3 weekly cycles, expected to feel nearly normal after last chemo. The break between chemo and radiotherapy was 4 weeks but as the fatigue and weakness continued and worsened during radio. Was difficult to know which side effect was from which treatment. However, when just on herceptin - no side effects. Can you talk with your breast care nurse, she should be able to intervene for you and speak with oncologist. You shouldn't have to wait the 5 weeks. I agree with you, is difficult to look at the long term when you are dealing with the immediate problems, especially nausea. Love to you x
