Three Years Out and band slipped

Have any of you had your band slip? I was loving life losing 80 pounds over the course of three years. A few months ago my weight started falling and I lost additional 15 pounds. I have always thrown up after I ate too much, but I wasn't even hungry...I went to my doctor , he asked me some questions and said he didn't think it was anything to be concerned about to come back in 6 weeks. I didn't keep my appointment 6 weeks later, but I started throwing up more and more. Last Friday I called my doctor after throwing up water, he got me in to see him within 45 minutes. My band had slipped he did surgery within 6 hours and removed it. The band had imbedded in my stomach he could not replace it. I am okay without my band and won't mind if I gain 15 or 20 pounds, but I am really scared I will gain the 95 pounds back I was so proud of losing. Have any of you experienced this? Did you gain your weight back? If I get the band replaced it will self pay this time; however, will pay in a heartbeat if I need too.
