I'm in the same boat right now. I have 2 more nutrition visits, and should be able to schedule surgery in December or January . . . BUT, I just started Keto. Cleaned sugar and carbs OUT of my house and my life. Made the decision, and realized that sugar was poison to me. I lost almost 10lbs the first week, and the weight loss has slowed down a little. I'm giving myself until December 15th to make the decision. If I'm still losing, and haven't been cheating, then I will postpone. My insurance doesn't reset until June 30, 2016 . . so I have until then for my deductible. I talked to my cousin, and asked her (she's on Keto, and had the sleeve 2 years ago) if she was me, would she have the surgery - she said YES! For her, (and for me typically), we are all gung ho on the diets for a month or two, then we fall off the wagon. I will most likely still do it, but I'm not going to rush my decision.
