Chemo isn't what it was 'back in the day'. Lots of gals actually are able to work straight through, some don't feel so good, and some are in the middle. I was one of those. I had adriamycin/cytoxin which is a very strong chemo 4 times, then taxol 4 times, every other week. I didn't feel too good during the first one, but was never actually sick - just icky for only a few days. The second chemo, I didn't feel bad at all! One just never knows as we are all different.
Telling you all this so you'll know that chemo is very doable. The anti nausea meds are amazing. Your Oncologist will explain everything to you. I have one piece of advice, if your gut doesn't like your Onc, go to a different one. You will be seeing this person for many, many years to come, so you have to feel very comfortable with this person. If you are able to ask questions and have them take the time to completely answer them, that's a good thing. Some gals take a friend/spouse with them to have another ear. That's totally acceptable with Oncologists. Ask what type of chemo, and take notes. I asked for a copy of my bloodwork every time they ran a test - which was right before every treatment to make sure my white blood count was OK.
Best of luck, and let us know how you're doing.
