Hmm, tried it for 2 weeks once when I got back from an especially booze fuelled adventure in India and thought some time away from my wobbly leg inducing friend might be in order. I got to the Sunday 1 week and 5 days in and crumbled into a glass of wine. Cheap South African Sav Blanc has never tasted so epic.
I'd probably find it easier now as I drink far less than back then so maybe i'll give it a try. I think it's more justifiable if you have a race at the end of the month mind. My race in Jan is right at the start so i'd probably get 2 weeks in again and wonder why the hell i'm bothering putting myself through this wholly unecessary torture.
They again, i'll be asking myself the same question 3 miles into the race.
