Same as me, by the sound of it, the weekly dose is likely to be a taxane. As @Shellshocked2018_ says, you can have a pattern through the three weekly treatments, and will know when you have not so good days and better days. Or like me, you may be just fine! I found A/C easier than my second chemo, Taxol, although most find the reverse to be true. Taxol was just more irritating, small side effects that cleared up after treatment stopped. It sounds like such a long time when you start, but it passes more quickly than you might think. Each treatment completed is one less to go. Best wishes.
