I just joined the forum, but felt like I needed to respond.
I had my band put in 3-07; was doing very well had lost about 25# in 5 months. My weight loss slowed and my new md (my original left the area) decided to increase the fill. I have had difficulty both times I reached 4ml.
I had too much fluid in, couldn't hardly eat anything, however I could get fluid in. My loss stopped, I got very ill, even aspirated several times and ended up with pneunomia becase of the "tightness"
I would suspect your band is too tight; you shouldn't have pain, everytime you eat (unless eating too much, or not chewing your food adequately).
I would suggest to notify your md to decrease the fluid in the band.
I think it is easy to get "caught up" in the excitement and think that more is better, when it really isn't. It's fine line when we fill. I have learned that patience and consistence with eating is of utmost importance.
