What a disgusting way to add sodium, when you can add salt to meals, ketchups, salted nuts/peanut butter etc etc
I never really went for sodium loading, but I've never had to make weight as I always competed in the open classes in bodybuilding
My tips are dispersible vit C in high doses, asparagus with each meal, push water high as possible in last week, a few glasses of dry white wine does no harm either
We used to use aladactone starting 3 days out
