There are creative ways to look like it's a real drink if you get to the waiter/bar tender ahead of time - twist of lime in sevenup, etc. You could say you are on antibiotic because of xyz (dental work, ear infection, sinus) and cannot drink alcohol. And attitude goes a long way - if you act like someone kicked your puppy because you can't drink well that is on you....if you yuck it up and make jokes, then no one is wizer. And I worked in IT - a very male dominated field, not to disparage my own sex but men are easier to get along with 75% of the time.
I had MGB in Canada in Sept/17. I was told that it was a less invasive surgery than RNY (one anastomosis vs 2) with fewer surgical complications, but similar outcomes to RNY. I had mine as a revision surgery 9 months after having my Lap-band removed. I lost steady in the first 3-4 months, but then slowed due to issues with hypoglycemia related to late dumping syndrome (blood sugar was spiking immediately after eating any carbs then dropping rapidly. Too much insulin production = poor weight loss.) Now that I'm getting this under control with medication, I'm losing again (only 14 pounds from goal). However, taking into account these complications, if I had to do it all over again, I think I would have gotten the sleeve.
