Should I be embarrassed being a 23-year-old man that still suffers from car sickness?
Why would you feel bad about that? Have you tried using the seasickness technique?
I can't, seasickness is different from car sickness. Seasickness happens when you are moving in the sea. So it would be impossible.
That's okay to be sick sometimes, it's not something you can grow out of. You just have to learn how to deal with it so you won't get embarrassed for the next time.
I'm not embarrassed. That's wrong because I had motion sickness before I hit puberty and I have it till this day.
Well I'm glad it doesn't embarrass you. But as you mentioned earlier you felt that you should be embarrassed about it. I'm sure you could seek out a doctor that could prescribe something to help with the sickness.
