Recovering from Caloric & travel

Hi guys,
I had my caloric test on Monday and it is Thursday today & I feel totally ruined.
In 3 weeks I am (supposedly) going to China ( 2 x 5 1/2 hr flights with a 5 hr stopover ) & a 10 day tour of the Great Wall. This has been booked since early in the year before my descent into hell began…
I have my specialist appointment next friday to review how I am going on my first trial of propranolol (diagnosis 11 August 2014) and i will need a medical clearance for my tour group.
the way I am feeling & what I have read about recovery from the Caloric Test, I may not be in any condition to go…does anyone have any positive information on recovery from the caloric?
