Hi there.   Recently had chemo for lung cancer.  Coped pretty well mostly but did feel awful on day 4, 5 and 6 after.   On a couple of occasions i became very light headed and actually fainted twice.   I took my bp and found it to be very low 60/30!  I lay with feet elevated for a couple of hours and felt better.    My question is could dehydration cause thisvto happen.   I had great trouble drinking and had to force myself.  Everything tasted awful even water and had no desire to drink.     I did try everything available to get fluid in but it was difficult.    Could not cope wirh being taken into hospital so did not call anyone but wonder if dehydration could have been the cause in case i need more chemo at some point.  Thanks Fay
