I love theme parks. I am a huge fan of roller coasters and other kind of strong attractions. The problem is that I usually feel sick fairly soon, sometimes even after the first or second ride.
That means that I usually have to stop riding for a while, not trying all the roller coasters in the park or just giving up strong sensations for the day.
Of course, that also slows down my friends, who often stay with me and don't ride (or ride less) the strongest roller coasters because of that. Besides, I cannot help but feeling that I am wasting money when I can't fully enjoy my ticket.
So my question is:
Are there any way to avoid or reduce this kind of sickness in theme parks?
Edit: my original question was worded with "dizziness" instead of "motion sickness" because a translation mistake.
