I had chemo ed today as we'll. I hope you had a great nurse and that he/she was able to answer all of your quezzies and help you feel better about your decision.
I thought if pass on a couple of things I've learnt while on here incase you haven't had the chance to see yet. There is a post on here about things that have helped others through their journey here -
http://www.bcna.org.au/user/9176/blog/28978. It gives some pearls on things that helped others. Baking soda and salt mouth rinses for example come up a lot. As do icy poles for mouth sores. There might be some ideas on there to help you.
For me, the main two things are having copious amounts of antibacterial handwash around the house and antibacterial wipes in the bathrooms. I found some hydralyte icy poles as well which I'm hoping won't taste awful next week because they will do great things for keeping me hydrated in this tropical weather!. Fingers crossed!
All the best lovely, take care
