Seriously - elevate your legs for an hour, it is supposed to help with varicose veins & jokingly - have a large vodka and coke and you won't care what you look like !!
If you fly to the states, you can get some really good anti-gas tablets from Walgreens that are fab, just don't take them during the flight as they make you fart like mad.
Hope you feel better tomorrow!!!!

Safe Flying all !!!
