What is going through Chemotherapy like?

Haven't been through it personally, my mom had gone through chemo. the meds they give you during and after chemo kinda keep you feeling less nausea. She was usually tired all the time, but I met people that were taking it and they were really energetic. So it affects each person in different ways, but there is one thing that all people will tell you and that is make sure you eat. no matter what, cause everyone says you get a really bad taste in your mouth and don't want to eat.
