I am half way through my taxotere, carboplatin and herceptin combo (number 4 i on Monday).
Sorry to hear you are having such a hard time.
I get the metallic taste, watery eyes etc.
For the dry nose (I get nose bleeds on occasion too),I found the best thing is Fess saline nasal spray (it is just saline/ salt water, but it re moistens a dry nose and flushes out any irritants like dust, pollen etc. It has cut my nose bleeds down a LOT.
I just spent a week in isolation with a neutrophil count of 0.00 (I am up to 1.8 now), so can have the weedkiller again tomorow. I have been put onto Neulasta now though, to try to prevent this happeneing again. they tested everything trying to find the cause of my infection but couldn't find one (although waiting for poo sample results as they were checking me for C diff, a NASTY bowel infection), checked my port, and entire body from top to bottom, was on IV antibiotics but after 3 days when they had to take the cannula out (as that can be a cause of infection if in for more than 3 days), they couldn't get another cannula in (and I am covered in the bruises from them trying). I got the lovely foamy green poo you talked about too, from the antibiotics. I am on oral amoxicillian duo forte now. My temp got to 40.6 before it started to come down <Eek>.
I hope you are feeling better each and every day.
My heart goes out to you, I really hope that your next chemo is better, and that you have no side effects from your next cycle. ?
