I get really tired of my diet too. I have to restrict fat, but not doing so good. I have set a maximum calorie goal of 1400-1700 and have a goal of 5-7 pounds a month. It worked in February. It helps me not to weigh myself every day and just stay in my calorie range. Sometimes we expect too much, too fast. But I figure 5 pounds a month would be 60 in a year. You could lose the 15 pounds without too much anxiety if you allow yourself 3 months
