I am usually pretty good on roller coasters (maybe a bit queasy feeling) but would get sick on simulators (like Star Tours) or spinning rides (like Tea cups). And when I say that I got sick, I mean that the best case scenario was that I needed to sit down for a while. More often than not, I was just hoping to make it to the bathroom before I got truly "sick". A person here recommended non-drowsy dramamine started 2 days before I would actually ride any of those rides. I took that advice and am so glad I did! I was not drowsy at all and was able to ride everything! I went on Star Tours 3 times in a row and the teacups two times in a row, spinning the whole time, and felt absolutely nothing. I also wasn't drowsy in the least. An interesting note, though. One time, I was unable to find the non-drowsy and just got less drowsy. It didn't seem to work as well. I didn't get sick but I could definitely feel that I had gone on those rides and didn't trust myself to do them multiple times in a row.
