I had my surgery done on November 4th and have not had any restriction to speak of since I had the surgery.  I've experienced no PBing, no feeling really full or sick, I am able to eat all foods still, etc.  I did lose about 8 pounds, but all from being on the liquids.  Because of this lack of restriction I was anxious to get my first fill.  I just had my first fill (1.5) about a week ago and I really don't feel any different. When I was watching my stomach under the fluoroscopy during the fill I felt like there was restriction, but I think it was all psychological.  It is cool to see the liquid flow through the band though and I do feel like the doctor gets better control by watching the barium flow through the stomach under the fluoroscopy.  
I have a feeling I am going to be one of those people who needs several fills before feeling that restriction that I want so much.  I know I should be happy that I am not feeling sick or PBing, but I feel like if I at least had this feeling I would know this was working.  Oh well.  I'll probably be back to Dr Ortiz's office in a little over a month for my second fill.  Dr. Martinez advised to wait at least a month before the second fill. 
Good Luck!
