Hopefully that will change. After my first fill I couldn't eat much for a few days, but then I was able to keep eating more and more. I kept going back for 1cc fills for several months that just didn't do much. I didn't really know it either, mainly because I didn't find or read this forum yet. The "support groups" at the Hospital were more of sales meetings for people thinking about getting banded than a support group for people after getting banded.
The time you have to watch closely is after a fill, especially when you start to get close to your sweet spot. It's easy to keep eating more than you should (even to "test" yourself to see how much you can still eat) after a fill, but it really does irritate the area around your band and can give you several days of hell if you irritate it. Constant sliming just plain sucks.
I had really given up on the band for being able to loose the weight I wanted to until I finally got the right fill. When you get it, it works. There is a "thin" line between love and hate though and you have to find it.
FWIW, I did Atkins for a long time around 1999. I lost 97 lbs and kept most all of it off for 5 years. Then......... Anyhow, I made Protein Shakes alot and they were pretty low in carbs, usually < 3 grams of sugars. I would use a scoop or two of chocolate Protein Powder (many differnt brands) and then use about 1/4 cup of half/half or heavy wipping cream, Splenda, ice chips and Water. I would blend it up into a real nice milk shake. I don't seem to be able to deal with all the air that gets into the shake when it's blended now so I just stir it all in a large cup. I can get 50 grams of protien in just one drink and it's very rich and creamy and good. Does have some fat in it from the heavy cream but is generally very low in carbs. Makes it easy to get all the Protein you need.
