Near the end of our flight; The B and the D [flight attendants] were finishing cleaning up the main cabin from the inflight service. I was in the aft galley cleaning up/putting things away. They had used a cart to pick up trash; it was a full 900. They barely made it into the galley and [FA D] asked if we felt the plane moving. I think we all said it felt like negative G's. Then [FA D] said she felt like she was going to pass out as well as she was feeling like she was going to vomit. All lavs were full at that moment; so she sat down on jumpseat with a big grey bag. All three of us were experiencing headaches; an odd strange feeling in our mouths; and we were all cognitively foggy/fuzzy. [FA D] phoned the pilots and they descended quickly and had an expedited landing. Paramedics met the aircraft to take vitals. We were requested off the airplane as they were finishing up. As we were waiting for new gate/plane; we spoke with supervisor on line as well as scheduling. We were told that we were physically unable to continue flying that night and had to go to [a] medical center. Possible other events may have occurred; but that is all I could recall as we were not functioning cognitively at 100%. We were taken back in the ER immediately and given pure oxygen. Blood work ran per discharge paperwork. We all had elevated Carbon Monoxide poisoning levels. We all experienced the symptoms of headache; dizziness; weakness; confusion; (possible) fainting; nausea; (possible) vomiting; chest pain; shortness of breath; and we all had strange effect in our mouth.
