I had my revision to bypass in August 2022 as well. I still get the foamies/slimes occasionally. It's strange but with the VSG I had experience dumping (fast heartrate, sweating, feeling clammy, malaise...Etc. but with the RNY, I experience foamies but no dumping. The only way I can stop the foamies is first, I keep blowing my nose when I first notice it, so no more will build up, then if that doesn't stop it, I use one of those tongue cleaners and rub the back of my tongue a few times, makes me cough and all the slime comes out. I remember in the beginning they would last for hours and hours. Now it's usually till I can clear it once. Last time I had it was after eating at a restaurant, on the way home in the car. I didn't have my tongue cleaner but used a chopstick from my takeout bag and an extra plastic bag. Eww. lol
