First of all, congrats on your journey and weight loss and second, yes, stress can definitely affect your band. but everyone is different. but in my case, i have always suffered from anxiety/panic attacks when under stress, and when that happens, i cannot eat anything. i have been banded almost a year now, and have done it all with only 3.7cc's, have not had a fill since last December solely due to that factor. but as i said, everyone is different and i would talk to your doc about it best of luck!
