I had my band removed in Sept. 2010 and had the bigger one put in Mar. 2011. Mine slipped too but it was because I was too tight and didn't have any removed so I was vomiting. Now I am extra careful. I just got my third fill Tuesday and now seem to have good restriction but I'm just on mushies right now. I am very glad that I got the band again and I haven't had any problems yet.
