Oh! Believe you me, I can relate to that. There is nothing that gets me more discouraged than losing weight and then gaining it right back. Poor food choices are always the bane. Excercise I learnt contribites just about 10% to weight loss, so once one is able to have full control over his diet, sleep and streessful life, then weight loss will happen effortlessly. Please, make bigger efforts this week like you've stated.
