I've never had any prescribed specifically because of my emet but I've taken several. Zofran doesn't usually make you sleepy. Promethizane/phenergan works but knocks you out. I had one other when I had my hysterectomy but don't remember the name. I'd already had a Zofran and it wasn't working so they gave me something different. Over the counter you've got Meclazine (less drowsy dramamine), Emetrol, Nauzine, Benadryl....
