Hang in there! I know a weight loss stall can be quite discouraging (I was on a 9 month long plateau in my own journey) about 5 years ago and TRUST ME, I know your frustrations.
Remember though, you don't have to lose weight every week to be successful. Remember too that while you have seen great success, weight loss is not a linear 1-2 pounds weight loss guarantee. If you have made the changes you mentioned, you need to give it a solid 4 weeks before deciding that the changes you made or are making work.
It could also be that you have reached the point in your weight loss journey where you are putting on some lean muscle mass (while shrinking the fat cells) and it appears that you are not making any progress, but you are.
Hang in there and know that you are making progress. Keep up the AWESOME job...I also included a link to part one of SparkPeople's popular series to read through. I hope this helps!
