I.e. to get back on it?!
I do well for a few weeks, then something happens like someone brings cake round or I bake with the DCs or there's a special occasion and it sets a wheel of bad habits back in motion. Argh!
I tend to need to be shocked into the right mindset, for example seeing a bad photo or catching my reflection in a shop window or something... but how can I rein it in of my own free will? Is it even possible?
