Congratulations on your jump back on the wagon! Keep up the great work!
Food can be so tempting. How about if you always carry a snack with you, one that is nutritious and yummy, so that you have an alternative on hand for when that temptation strikes?
Do you count points or calorie count? Then I would also include that snack in those totals, making yourself accountable for your choices.
Also carry water. I find that guzzling water sometimes distracts my mouth/taste buds/stomach from tempting food.
Lastly, how about some plain tea (including herbal/fruit)? No sugar, no milk, no calories -- just flavoured warm liquid that will fill you and give you taste and a chance to 'purchase out', without the caloric effect.
I can imagine how tempting it is. You are doing so well in trying to break the new cycle. You can definitely do this! Good luck, and I can't wait to hear about your success down the road!
