Honestly I was so surprised at how long it took for it to completely heal when I had mine out, I'm sure it was painful for at least a good 5 days if not a whole week (although gradually improving). I'm sure I ate some tomato soup on the night of the procedure (I had it taken out early afternoon I think). I didn't get dry socket or anything. Mostly I ate tinned tomato soup (not too hot though like you said), yoghurt, bread and butter. Like you I was permanently hungry and couldn't wait to be able to eat properly again! I really underestimated how long the pain would last.
