Hi Sarah,Yes, I do, I too get weepy and fatigued the day after my Herceptin. It may be purely psycosomatic, a response to being confronted once again with the fact of having cancer and of losing the sense of being immortal that we take for granted. Or it could be part of the inflammation of mucous membranes/flu-like symptoms that are trotted out as standardly part of Herceptin. Or it could be just that suddenly my health and energy levels drop and it is distressing to feel more fatigued etc.
best wishes
Jessica
