Great Job...before you know it, it will be second nature. Then you will be a frugal addict like the rest of us
I try to ask myself do I "need this" if not, I really try not to buy it.
Junk food for example, I tell myself, it saves us a lot of money, and my wasteline too..

No junk food in house, save money, and no temptation.
I also ask myself, can I do this cheaper, or buy this cheaper.
My biggest weakness is eating out. I only eat out once a week or every two weeks, and it usually is MCD...a no, no for good health...I am trying to get myself content with going to MCD and getting a salad with chicken, small fry, and diet soda. around 3 dollars.
I also try to do like most of us, and clean out my stockpile before shopping again. I usually buy milk and eggs every 2 weeks, but other things I usually only go grocery shopping once a month. Since I have a deep freeze, I use Shop N Save's 10 dollar off coupon, at Schnucks when they have one, and buy our meats.
Being frugal is an addiction. At least it is a good one!!
Keep up the good work!
