Hi Olga,
A big welcome to this site. There is a wealth of information here through all of us who have been through what you are just about to experience. I had 4 rounds of chemo from January to March this year, for a grade 3, 21mm tumor.I had no nodes involved, amd my chemlo was Taxotere and cyclophosphamide. I was lucky and didn't experience bad side effects. The oncologist will send you home with lots of different medications, and my advice to you is to take it, as it is much easier to prevent nausea than to treat it. I found the nausea a little like morning sickness, and it was relieved by eating little amounts often. I also wrote down all symptoms I had, what medications I took, and how they helped. This is really useful for the second cycle so you can be prepared. One thing I discovered on my last cycle, was that the clear lime or lemon flavoured flat mineral water tasted great. I wish I had known this earlier, as I found that water tasted so foul, and you really need to drink. Somehow this mineral water over rode this taste, and it was really refreshing. The other thing I wish I had done was take more photos. It never occurred to me to take any while I was having chemo, and now I wish I had a record. I didn't even think to take a picture of my bald head until my hair was growing back. At the time I probably didn't want to be reminded of it, but now I regret that I didn't do it.
All the best for tomorrow, and please feel free to come onto this site and vent and rave, or complain or whatever. We have all been there, and know how you are feeling.
Love Chris xx
