Still nauseous at 21 weeks

This is my first pregnancy. My whole first trimester I would throw up anywhere from 6-10 times a day. Ended up having to stay a night in the hospital for dehydration. They finally gave me zofran which did wonders for me when phenergan did nothing and unisom with b6 did nothing. I still have to take zofran every single day at least once. I figured by now my nausea would be gone but nope I’m afraid I’ll be taking zofran this entire pregnancy which I hate to do but the sickness interrupts my entire living. After going through this and all of the other issues I’ve had this pregnancy, I’ve decided that one child is enough for me. But my husband still wants two. I hate to do that but I don’t physically think I could ever go through this again. I’ve been miserable for months now and I hate being pregnant. I just keep wishing October would just get here already. Anyone else feel this way or have felt this way?
