So ((hugs)). The standard advice on this is to quit watching My 600lb Life.
I get you. I really do!
You're thinkin', "Dayum shazam! I just rearranged my innards and am eating like 200 calories a day. I should be losing more weight each week. If I wanted to lose only 10lbs per month, I coulda done Weight Watchers!!!! Gimme that cool 25-50lb per month weight loss I imagined I would experience! Cuz 10lbs a month! Dayum, I feel ripped off!!!!!"
Also, as for the surgery sequence of going from RNY to sleeve...Inconceivable (youtube clip)! I do not think that means what you think it means! I think maybe you aren't very familiar with your tummy anatomy. It's why so many have responded with a kinda sorta...WTF with a screwed up question face.
For most, the sequence of multiple WLS would be Lapband (maybe), then VSG (sleeve)...then duh duh dunnnnhhhhhhh! No weight loss or loss and regain or reflux or...CRAP! This surgery didn't work and now I need a more drastic surgery that includes malabsorption and a further reduction of tummy capacity/food restriction--which takes you to an RNY or DS. Cuz you know, you're jonesing for the magical 25lbs a month that Dr. Now's patients see...
But sadly, the reality is that your surgeon will be as happy as a leetle girl if you maintain a 9-12lb per month consistent loss over the honeymoon period. That's 120lbs in a year if that happens consistently. Which is damn skippy in my book!
The next step for a more drastic surgery than you have right now is to go from an RNY to a DS (duodenal switch)--which put simply, include even further malabsorption. And you are sooooo not there yet!!!
So keep on keepin' on and sip, sip, sip, chew, chew, chew. Don't eat around your surgery and follow the rules from your surgical team, and you WILL lose your weight!!!! ((hugs))
