My usual routine for leisure flights in F/J:
In the lounge:
Three glasses of champagne before lunch
Two glasses of wine with lunch
A cocktail before coffee and dessert
On board:
Two glasses of boarding champagne
A gin and tonic after take off
3 glasses of wine with lunch/dinner
A glass of dessert wine
A digestif
Then an ibuprofen and as much water as they will give me!
