Hey, I completely understand your frustration! I'd like to point out a few things though. First, losing 4 lbs. in one week might not accurately reflect the situation. You may have lost 2 lbs. of fat one week and 2 lbs. of water and then the following week, say you lost another 2 lbs. of fat but it didn't show because the first weeks' water loss masked it. I hope that makes sense.
Also, have you read any of the posts written by Kaplods? She has really helped me with the whole time limit on weight loss thing. I could never do her justice by trying to paraphrase all the wisdom she has imparted on this board but I highly recommend you do a search on her posts.
Finally, there are times when we might need a little bit of a dieting break. That doesn't mean all heck should break loose but maybe you can allow yourself a treat? Maybe one day a week? That might keep you going. Or how about rewarding yourself whenever you accomplish something that's not weight related. I know it sounds crazy but why not reward the fact that you stuck to your plan for a week? Or that you exercised 5 days in one week. That way, you're not placing so much emphasis on those numbers on the scale. Weight loss isn't always fat loss so the numbers only matter over long periods of time.
I really think that a lot of people throw in the towel on weight loss because they feel like it's not happening fast enough or they feel like it's not happening how it's supposed to.
I really hope you hang in there! You're doing so great! Don't give up now. And you know what I did? I recently gained back almost 30 lb. for a bunch of very good excuses but the truth is that the food was only a temporary fix which eventually made all my problems that much harder to deal with.
