It is hard, when we lose focus. I've had a lot of solid months but the past 4 weeks have really been all over the place. It serves as a reminder that the band doesn't solve the issues and that it takes a lot of hard work.
I think its a positive that you are able to see where you are, but also where the issues may be. Slider foods being a big one. Stop at every meal and see what you can do to turn it around to being drier, crunchier, and protein based. I find that if I physically stop and think about it, it helps to make better choices. My band is always tighter during the day too, although I'm going for an emergency type appointment on friday because all of the restriction I did have has literally disappeared one night, went to bed not being able to eat anything, to waking up being able to eat a horse!
it sounds as if a fill may help you, and if you find that it motivates you, perhaps small but more regular fills may also help with the way that you eat. And its good that you're going to see someone about the eating habits. It sounds as if you're on the right track . . .
Keep a diary, log everything, and I think we are the only ones who can kick ourselves, I've a bruise on my bum after a dreadful weekend of eating.
Good luck to you!
