Only taking antagonists which would be rather difficult to attain and would probably not offered clinically unless you're at risk - if you're not in danger, you don't need to go to an ER or call an ambulance for a shot of narcan (naloxone).
If you're just uncomfortable, you can try to relieve the nausea such as by laying down or whatever you have found success with but there isn't a way to abort the high without antagonists.
