Sending gentle hugs and mega prayers your way my friend. Hoping the 3rd day yuck is past and things will begin to look up. Mouth sores are one of the side effects I remember most (other than hair loss), but the mouth wash I got helped considerably. That must be part of Taxotere.
Take it easy and get your strength back. Love you - crabby or not - and you have every right to be crabby.
