It's normal to be nervous! My chemos were always in the morning. I usually had a pretty good breakfast funnily I actually got hungry during chemo. I would just have a light lunch and see how you go. As for drinks water, water, and more water. A friend gave me a tip to half freeze bottles of water and top them up with cold water in the morning. That way you have lots of really cold water to sip on the whole time. Apparently this helps you not get mouth ulcers. I did this and never got any. Not sure if it was a fluke or not. They usually bring around cups of tea etc. wishing you lots of luck tomorrow. Go zap those nasty cells away!!
