The month following my 2nd fill

So about 1 month ago I had my second fill. That week or so  I lost about 5-7 pounds. During that time I was stuck a lot. Over the last 2 1/2 weeks I have gained that 5-7 pounds back. I can't imagine eating less or getting another fill in November. I am going to log my food over the next week and see if that helps me figure some thing out. Someone mentioned too many carbs or not enough carbs. I am not sure how many calories I eat a day but It is what I was told to eat. I haven't been exercising but that is because I am so exhausted all the time. I have an appt with my GP next week and my WLS doc on 11/2.
