I was a grazer too but now i have set times to eat. As my son is type 1 diabetic, he has structured times where he has to eat so i do to.
Breakfast at 8.30
Mid morn snack at 10.30
Lunch at 12.30
Mid pm snack: 3.30
Dinner 5.30
Bedtime snack at 8.30
This works for me and i never get hungry. I have my meals at the stated times and at snack times i have fruit, yoghurt or my syns. x
