RE: Water Retention!!
Totally agree I drink 8-9 litres the day before (of water that is)and cut it at 6pm. Start the wine with the meal. A nice Jacobs Creek does the trick and polish off the whole thing. You'll be getting up every 30 mins to urinate but you wake up dry as a bone. The day of the show I take 1000mg of vitC and suck them without water every hour, this dries you out further
