I used to have a DJI FPV that I really liked but the damn goggles gave me a crippling migraine after I wore them for more that 5 minutes so reluctantly I sent it back.
After discussions with the doctor he changed my beta blocker prescription to a different one, just spend the weekend testing out with a borrowed pair of goggles and no migraine! Even after an hour I was fine 
Looks like I’m going to have to buy the thing again.
