Edema after fat transfer, when would it go away completely? What can I do to help? Supplements?

I had fat transfer 6 weeks ago. At first I developed a moon face. As it subsided, the swelling settled in my jowls and jaw.. I look boxy with a big chin. Few days ago, feeling depressed I had a long cry in bed, and to my surprise I woke up the next day to a beautiful V shaped face. But that didn't last long as the swelling came back the next day and I look squarish and saggy again. I suppose the tears reduced the sodium in my body, which temporarily took away the edema? I love salty foods.
