Almost there...I hope

Hello everyone! I am new to this site and I am so happy I found it! I began my wls journey on September 1st and I am nearing the end of the line. I’ve had my bw, GI, Endoscopy, psych eval, and I have 1 more nutritional class on Monday. I am hoping that everything goes through and my insurance provider approves the surgery. I am just so ready for it. I was kinda nervous about the approval because although my insurance doesn’t require me to lose any weight I did gain about 4 lbs since my initial weigh in and I thought for sure when they submitted my paperwork I would automatically get get denied because you aren’t supposed to gain any weight. I asked my nutritionist about it and she said as long as I am back to my initial weight by the time I sign my surgical consent then I should be good to go. I have lost the 4 lbs that I gained and I go for my weigh in and last class on Monday. Anyone have a similar situation and if so what were the results? Also about how long does it take to get approved once all the paperwork is submitted? I am hoping for a date in February or March.
