Hi Leanne,
Great to hear that your first chemo went well, it sounds very much like my first one; very long day and I nodded off a few times :-) I was told the first infusion is delivered very slowly so that they can closely monitor your reaction and if all goes well, each time after is a bit quicker. I think by the end of my 6th cycle of TCH I was down to about 4hrs and having the Herceptin on its own was quite quick, usually about an hour and a half, just time to enjoy a cup of coffee and go again!
I did get some heartburn / indigestion with my chemo and my oncologist prescribed Salpraz, so just chat to your doctor and they'll be able to help.
Best wishes, Jane xx
