I am quite amazed at how much my edema was being caused by my addiction to real sugar Pepsi. I have lost about 10 pounds of fluid in my legs, from simply stopping all Pepsi consumption, and only resetting yo drinking Dr Pepper when I have a gnarly headache.  I don't know why it works but it does. In general my headaches require acetaminophen and ibuprofen together. But on days that doesn't cut through one or 2 Dr Pepper can get it done.  It helps that I don't like the taste of Dr Pepper, so I don't want to drink it just because.
