Welcome to SR Pumkinface
I know I wasn't reaping the benefits at a few months sober. I am not sure how long it took for the puffiness to go down but I think it was months. I remember thinking though that that is how I must have looked for years but I was too drunk/hungover to notice/care. Maybe check with your doc what vitamins you should be taking and whether low sodium is a good idea...
Well done on a month sober anyway! It does get better, it just takes time.
