At this point it would be not only difficult, but impossible for me to live with an artificial flavoured family. I would go out and camp in a booth. :-) By fasting with a family you are playing mission impossible.
I'm using a traditional hand made soap that is flavoured with real honey, but even that feels a bit repelling. This soap is already a replacement to my previous artificial one that became repelling even without fasting. I was just wondering what on earth could I use to have a bath, wash my clothes and to give the flat a nice scent.
To give the flat a nice flavour I remember that during Christmas we always put the peel of orange on the stove, I could do the same... And maybe research how to extract the smell of some other fruits, the green pears have a really nice mild and sweet smell.
