About to start chemo &herceptin

Hi all, finally finished my taxol and herceptin combined doses and have had two out of 13 herceptin three weekly treatments. What a relief to feel almost normal again. Have been going well, up until today, and I feel very tired, and my eyes are bleary and heavy. Have I pushed myself too much do you think? I have been slowly getting into housework although not heavy things like vacuuming etc. I minded my almost two year old grand daughter on Wednesday but I rested when she did. What is worrying me most is my eyes, they get bleary and at times my left one seems to be looking through a fog. I know chemo can have some effects, has others here had similar? Interested to hear from others that hav been down this track Regards Jill
