Yes rides make me sick, and yes I still ride! It's "H-E-double hockey sticks" to love something that makes you want to puke!
Ask you doctor for a prescription of "Scopace" (scopalamine). It's the same drug that's in the patch that many people use on a cruise, but it's in pill form. Practically NO side effects, other than it gives me HORRIBLE cotton mouth, but it DEFINITELY helps. I've even successfully gone on some spin and pukes and lived to tell the tale!
Even with it though, I still have my limits. The Voyage at HW can only be ridden about twice before I need to recover. The Raven I can get in 5-6 rides before feeling like I'm pushing it.
The other thing you might consider is avoiding caffeine on ride days. That's definitely had a positive impact on me as well.
