It is great to know that you lost more than 15 pounds in the last two months. It actually shows the discipline that you have maintained and I hope you’d be able to lose some more weight as is needed,in the coming days. You being a selective person and always having a habit of comparing prices and saving something is again a good quality in you and it’s important as well because money does not grow on trees but has to be saved wherever there is an opportunity. I think walking around the market would have also helped you with some calorie burning. Anyways you are on a right path and stick to it till you get back to some normal weight and completely get rid of inflammation and pain.
