I'm 4 years postop and have also regained. I initially weighed 305 - lost down to 195, then on year 2 gained up to 209. Panic set in. I joined a "Quick Weight Loss" diet plan and lost 30 lbs on a VERY rigid diet (carrots were forbidden b/c they have sugar!). Needless to say as soon as the diet ended, the 30 lbs came back, along with more. Now I weigh 215.
Here's what I'm trying to do...I'm working with an eating disorder therapist using the "Intuitive Eating" approach. That's a book I highly recommend to all of us with eating issues. I'm also trying to be grateful that I weigh 215 and no longer have hypertension, gastric reflux, joint pain or sleep apnea. The truth is if I'd not had surgery 4 years ago I'd probably weigh 350 by now at the rate I was continuing to gain weight!
I'm also trying to forgive myself for being human. Many many years ago, I learned to use eating as a means of survival and coping. Not a healthy means, but it has gotten me to this point in life. Now I must be kind to myself as I learn new ways to live.
Congratulations on the postop weight you have acheived and continue to be as kind to yourself as you possibly can.
