Got airsick for the first time ever

I’m around 90 hours into my flight training and while practicing some IFR under the hood with my instructor, I threw up all over myself while going back to the airport. It was a clear day which obviously meant it would be pretty bumpy but I didn’t expect it to be bad enough to make me sick. I haven’t thrown up since I was a kid since I have a pretty strong stomach so this is a really strange occurrence. Has this happened to anyone late into their flight training/career? I just feel so embarrassed and discouraged…
