Gary,
I think the treatment started on March 1st, not Jan 3rd. The Brits write dates differently than us Yanks.
Cookey,
It's awful soon to be going through the side effects you mention. The treatment hits everyone differently and not knowin Robin's dosages it's hard to say why this has all started so soon. Cathy is right though, you need to see the nutritionist ASAP. Also speak with his Docs about the early onset of the moth sores and pain. Did you say whether Robin had a PEG tube or not. Hang in there you have a very long way to go yet.
