That is a lot!!
I only do that when on holiday in a new city normally.
Strong choices take energy... but after a while... they start to bring some energy with them, too.
This is why when changing to a new habit, "make it easy" is so important at the start. Too much, and it will fail due to the energy it takes.
Twelve kilos down since the beginning of the year, about eight more kilos to go...
That is massive! Well done!
