What kind of side effects?

[marystro]

Just came back from Beijing after a 4 day trip there.  Plane ride was fine.  Actually got a lot of sleep.  My boss upgraded me to first class fearing that I might have problem with the long haul ;-).  Tinnitus has gotten louder a bit and tiny headache although not all the time.  I am not taking any aspirin nor tylenol yet since it's only very slight headache.  I understand that tinnitus would get worse and should get better later.  Does anyone know how long the louder tinnitus will last?
