I get motion sickness pretty easily, and for that reason had held off on going on ToT because I was convinced that the up and down/drops would make me sick. I finally decided to just go for it last month at Disney World, because life is short and I want to have no regrets, such as regretting having never tried something like ToT. So, I did it. Immediately after having gone on Rock N' Roller Coaster, which has loops and is in the dark!
My verdict? Not bad at all! The theme was nice and spooky. I was terrified the entire time leading up to the ride, and it was all I could do to not exit the ride once I was strapped in. But I stayed, and it turned out fine. I didn't get sick. I screamed my head off. I kinda liked it, really! I would absolutely go again.
The ToT in Disney World is unpredictable, each time you go is different. You never know if you'll drop a few times, or many more. My experience, we dropped probably 6-7 times.
Long story short: I get motion sickness, but was able to go directly from a dark roller coaster with inversions to ToT with no issues.
I hope you get to try!
Edit: I should mention that I did take Dramamine (less drowsy formula) daily on my trip, so that probably helped me keep from getting sick. Just full disclosure!
