It used to be that chemo made people so sick, but the anti nausea meds now really have resolved that issue. I had 4 rounds of A/C and four of Taxol. Every other week, so it took awhile. That is a very common combination, but may not be what's required for the type of BC you have.
I went in on a Friday. I felt pretty good (anti nausea meds gave me a little headache), for a couple of days, then icky (needing to rest) for 3 days, then fine till the next chemo.
Everyone is different, so there's really no way to know how you will respond. Some gals work right through chemo. I was 58 when I started and I did work part time. If I needed a few days, I was able to take off.
The best advice I can give you is to be sure that you start hydrating now to get your body used to drinking a lot of water. Not soda, but water. It's really important for many reasons.
Oh, if your surgeon didn't give you any arm exercises, please find out if you can do them. My surgeon had me "walk" my hand up a wall a few times every day until I could get my arm stretched all the way up. Had I not done that, I may have needed physical therapy.
Let us know how you're doing. Thanks for checking in. You'll do fine.
