some fluid removed but lost 6lbs

I had to get more taken out of my band than was put in on my last fill because it was too tight. For the last two weeks I have been able to eat like I did before my second fill. I could have sworn I was going to gain, but instead I actually lost 6lbs. I did start the month off with a lot of exercise daily, but as the tempature got into the triple digits I didn't even bother. I just wanted to post this too let some of your who has had a month were fluid was removed not to freak out, instead exercise and try not to get obsessed about lossing. The more we stress the less we loss. Stress can also cause weight gain.
