Ah, well, leave it all behind and . . .
What will change is that I will count up rather than down. I shall keep running totals of how much I could have spent and how much I actually have spent. Hopefully, the latter will be less than the former.
I shall run it from month to month now. Starts of the first day, ends on the last day with a weigh. Much more sensible.
The left over money from April will buy some more apfs to start May off. Things like butter, oil, herbs, yogurt, etc. Works for me!
