No, I ask this question since last year I went 4 weeks into Lent without drinking a coke since I gave it up but then it was Sunday and someone offered me one and explained to me that I should not be giving it up on Sundays. To me, this kind of defeats the purpose when it is just one desirable item. I would say most people can go 6 days without something they like knowing they can splurge in it on the seventh. It would be a sacrifice but not a hard one. An exception to this would be all meat or all deserts or all sodas. That would be such a hard thing to give up for all 6 1/2 weeks that one should enjoy it on Sundays as it is the celebration of the Resurection. However, any little item like chocolate, coke, candy, one specific kind of meat, etc. is too easy to just give it up for 6 out of 7 days. Also, Jesus didn’t go to the desert for 6 days, come out for the seventh and have a party and then go back.
