I'm on soft foods too! Oh man, beef sticks sound awesome! I would just make sure it's not full of any added sugars. I had about a quarter of a beef hotdog this weekend and it settled well. Just make sure to chew chew chew!
I had gained as well around my 3rd week. I was dealing with an extended menstrual cycle because of the blood thinners, and I truly believe it caused me to keep extra Water weight on. It's finally calmed down and I'm losing again! You'll get over this hump!
