Jen - My worst time for bad eating is after a bad W&M. That does not help anything, trust me. So please do not get discouraged.
My big whoosh was around the 3 month mark. My first W&M came after ~2 weeks of "vacation", can you say gain? I stuck with it because week 2 of "vacation" was for my father's bypass surgery. All went well, but he was in better shape than me. So, I kept it up. Had a small loss for 2nd W&M. Third was awesome, though. Your hard work will pay off!
