Welcome Georgia! I'm up in the air about the refeed thing. That may be because I really haven't read up on it--just picking things out of various threads I've read.
Carbs still trigger overeating of them for me, so I'd have to be very careful about which ones--they definitely couldn't be sweet (as in fruit or even sweet potatoes, etc.). Once I'm well on my way with this I may try a potatoe or two every few weeks. I don't now. Eventually, once I've lost most of the weight I want to lose, I will definitely add back things like potatoes as a more frequent treat (I think, lol).
