It's good to face the fact that you're unlikely to get as much done as you're usual caffeine filled self, so pick a week when you don't have a lot on and there's no looming deadlines, dinners with friends, or boozy nights out planned. Weekends tend to be the toughest time, so I'd suggest starting on a Monday so you can use the motivation built up through the week to  keep you strong at the weekend.
