Hi Julesy,
Glad to see another kiwi too
I agree with Lizw and flutter about changing your routine. Cooking dinner is one of my trigger times too. Is it possible for you to prepare some of the ingredients in the morning or the night before, so that in the evening you don't have so much to do, and don't have to linger over making dinner which is your trigger time?
Or if you have kids, get them to come and help with little tasks, then it becomes family time, and you will be busy talking to them, which can be a welcome distraction from inside your thoughts.
Congratulations on making it this far, too that is awesome!
