Hmm, “to get your money’s worth” sounds like codespeak for “I don’t trust God to provide for my needs” which is an entirely different problem. I would say to eat as long as it’s properly pleasurable is fine though - you can skip or reduce a later meal to adjust if wanted. Gluttony seems to lie in the intent and not the amount, even per sitting, and perhaps could be defined as an inordinate attachment to food. Some people might commit gluttony with amounts of food that in others might not amount to any sin. Any attachment to a created thing over God is a sin. Everything in its proper place. Try to read your heart’s intention - are you eating out of necessity or simple pleasure, or are you eating because you are addicted to food? Ask God to help you discern, but in the meantime the Church has its own discerning mechanism - fasting. This helps keep food in its proper place as a good, but under other higher goods. If you’re not in a position to fast, for example, because of legitimate work concerns, you could try a psychologist, or trust to your insights in prayer. Even small sacrifices could help you discern if the food is controlling you. But don’t forget to celebrate with the pleasures of the plate when it’s the time to celebrate. God bless!
