Hi Robyn, it's absolutely natural to feel anxious about chemo, but for the most part it is quite uneventful.
In my experience, the oncology staff are brilliant and get you at ease very quickly. They usually take it a lot slower on this first cycle so they can monitor you very closely. My first chemo session (taxotere, carboplatin & Herceptin) took almost 8 hours, so was glad to have my hubby to talk to, my ipad, magazines, music etc.
The following week or so may be when you feel the effects, but tell your oncologist about any side effects and they can usually be minimised, so don't tough it out! Best wishes, Jane xx
