okay good news that you are making progress.
so you'll get zinc, mag and the other results in a couple weeks, and hopefully the other tests requisitioned next week. great!
and if you have the epsom salts, that's even better - don't exceed whatever the package instructions tell you though
careful with raw chard... you need to boil it for three minutes to remove the oxalates. a big green salad containing some spinach is fine, as long as the other greens are low in oxalic acid. cooked spinach needs the same treatment (ie 3 min boil) if you consume it in high volumes.
looking forward to seeing your updates over the next few weeks. hope you can try the epsom salts soon! i'll see if i can help you get some ideas for good mag supps. ttfn!
