@Trikki2 I did a salt water rinse three times a day through the first two weeks of the three week cycle of TC. My mouth tried to get an ulcer once, in the fourth round when I was massively run down. But it backed off very quickly as I kept doing the rinse.
I bawled for an hour at my first chemo, 20 minutes at my second, 5 minutes at my third and was dry eyed at my fourth! I had a counsellor I saw during chemo which was a big help. Have you got a professional to talk to? Big hug, K xox
