Took me about a week and a half. First day in VR was so bad that after 20 minutes I had to take it off and lay down for an hour, didn't feel back to normal until the next morning. 
Things that helped prevent me from refunding VR;
>Playing while seated (VRChat was easy for this)
>Fan always placed in front of me
>Never on a full stomach and always well hydrated
>Removed the nose guard (which had a very synthetic smell out of the box) to breathe easier
