Weird Question

This is my first time posting on here. I was doing really well. I am at the end of losing weight and hopefully soon will be concentrating on maintaining, but over the last month or so I have been eating a lot at night and not all of it good, I eat healthy throughout the day and then at night sometimes I snap and eat a lot more than I should. I do intense workouts, advanced Turbofire and I was looking so lean and trim. Now every time I look at myself in the mirror I feel like I look huge. I have only gained about 2 pounds because once I am back to eating healthy with my workout regimen then the scale goes down within a week to my normal weight. Everything feels tighter this time though. I fit in all my clothes and everything but feel like my butt grew is that possible even though my measurements didn't change inches wise? I am back on the wagon now, but curious how long anyone thinks it will take of clean eating and working out (I workout at least an hour 6 days a week plus walking) before I feel normal again. Is some of it just puffiness or did I really gain a lot even though my inches and the scale tell me I haven't. I know you can't really answer but any suggestions or anyone who has been there who could respond I would really appreciate it.
