I have unintentially missed packs here and there, but never bothered to have an extra the next day - the weightloss hasn't been slowed and I didn't feel worse off nutritionally - I think others have said, so long as it isn't a really common occurence it shoudn't make too much difference - so far as the nutrition goes even on a missed pack once in a blue moon I can guarantee in my case that the nutrition going in that day would be far superior to that going in on a normal day prior to LL!
