I didn't get tested for food allergies , come to think of it. I don't know why. My allergist is very good, but for some reason, he didn't take this route. I don't remember if Lakemama discussed whether to keep taking the vinegar water long term after it heals the eczema, although she did say to keep with it because it took three weeks for it to work. Hopefully, depending on how well it works for you, your body will let you know whether and when to stop taking it.
