No, you're not the only one who has felt this way.
My last fill was a little iffy. I was certain when I first got it that I needed to get some taken out - It hurt to drink Water. When I realized I just had swelling from the fill I waited it out.
As the month went by I was losing a ton of weight and not getting hungry until the afternoon. It was great.
I was afraid that they would decide I had lost too much weight and want to back me off. But what I've learned over the past month is that the band isn't too tight, I just need to get used to having proper restriction (chewing a ton, eating slowly, etc.)
It does sound like you did the right thing, good luck!
