Sole for Salt Loading?

For a long time I didn't do any salt loading, as it seemed to me I wasn't experiencing any detox symptoms even on relatively high levels of iodine. I did salt my food liberally with Real Salt, and I thought that was enough. I was taking the co-factors - B2, selenium, magnesium.
Over the winter though I got a humongous cold. I rarely ever get colds but this was something else and it went for a few weeks. Even after it calmed down, I was still very congested even though I cut out pasteurized dairy and other stuff. Finally I decided to try salt loading - a half tsp. in warm water followed by 16 oz. plain water. Wow! I felt better immediately, and this made me a believer. I'm still not sure whether the cold and congestion were detox symptoms from the iodine, but since then I've been doing that daily first thing when I get up.

I've been reading about the benefits of salt & water, and considering making sole. I was looking at the messages about sole, to find out whether sole can be used for salt loading. No clear answers, so hoping I'll get one here. Thanks!
