Hello, go walking is right. You may have to have many fill to get it right. But please don't do what I did, I was sent to a dr who was filling me almost weekly, I did not know any better, wasn't told that was not the right way and basically was a cash cow (super pun intended). All I wanted was to loose weight, and that is all I cared about. This was in 2005. The band was so tight, I couldn't even drink Water. I lost 100 lbs, but it made me sick constantly, even when saline was reduced. I lost because I couldn't eat anything and went back and forth with throwing up, et. It was starting to mess up my esophagus, so surgery dr recommended to take it out. (This was a different dr from who was going me fills, but he didn't care about me anyway either. As long as his personal plane was paid for.) Anyway, I went out with any saline for 6 months and tried it again, more slowly. Long story short, it has made me sick and pain no matter what I eat and sometimes drink.
I hope the band does not give you the problems I've had. I hope it works for you, because I know what you are going through. Take your time, make sure you stay healthy, cause no amount of weight loss is good when you are sick or malnourished behind it, believe me.
I just got back on here because now I have a sleeve. Took out band on 3/24/2014 ( self pay, that is why I had band in me so long, 2005 until now.) Please feel free to ask me any questions or email me.
