Hi Helen,
Sorry you aren't feeling well. I felt dizzy with the AC as well. It worried me and i found that dizzy feeling hard to deal with. It wasn't something they had mentioned in the education session, nor could they explain it. The my oncologist and nursing staff didn't seem concerned. I have read lots of posts here about people experiencing that dizzy/ lightheaded/ heavy headed feeling. At least I got some reassurance from this site. I would say keep the fluids up, take all the the recommended medications regularly as directed and contact the chemo nurses if you are worried or don't get relief from what you are currently doing. For me each cycle was different. The first was a struggle the first week, the second and third much easier and the fourth harder going.
As for neutrophils, each centre and even each oncologist will have a slightly different range within which they will go ahead with chemo. Generally between 1.0 and 1.5, taking into account each individual and their circumstances.
