Not only hamburgers, I switched to a plantbased diet so I mostly eat vegetables, fruits, nuts & seeds. I've been on it mostly for the last 2 years but do still have the occasional relapse though. Once I'm in the flow putting some time into my food it's pretty great and I don't really miss it. At times when I'm really busy or have a lot on my head it's still tempting to let myself go. Overall I'm managing quite good though.
