I meant to say earlier malt, I always got very tearful and abit snappy about a week after chemo, - it is the steroids that do it - make you feel shit, so that will definitely be adding to the way you feel.
has anyone suggested that you keep a little diary of how you feel each day during your cycle?, - so you just note down your indigestion, low mood, sickness or whatever, and the day it occurs. It is very helpful for next cycle, - you can see how you felt, and see also when you started to feel a bit better, and you will find there is a bit of a pattern probably. And it helps in dealing with things when you know what to expect.
Remember - this first cycle is a big learning experience, everything is an unknown quantity to you atm, - you are getting used to how your body deals with the chemo you are having, - everyone is a different, and your experience is unique to you, - you will become the expert! 
Also if you have it written down, it is easy to look through and make a list of anything you might want to chat to the oncologist or nurses about next time.
