From 1st January 2012 to when Ironman Wales 2012 is over, I will not be drinking any alcohol. (There may be 2 nominated exception days - the day after Ironman UK 70.3 and perhaps 13th January - I've not yet decided whether I will do that or not.)
It's just going to be easier that way. Easier to keep to my planned nutrition - alcohol tends to lead to eating more than required/planned. Easier to keep to my planned training schedule - alcohol leads to poor quality sleep, lack of enthusiasm the next day and is pretty poor nutritionally. It'll just be easier all 'round if I don't drink at all. Drinking a bit, setting a weekly/monthly limit isn't going to work. It's all or nothing 'cause that's how I am. I'll miss the wine, for sure, but some things are worth quite a bit of sacrifice.
Stopping right now isn't something I need to do, nor is it all that practical when there's wine in the house ready for Christmas, so the date is set for 1st January.
