The immediate answer that comes to mind is that our electrolytes are out of whack. I have not been doing the SWF, only the lax tea so I have had NO sodium in 9 days- if you're doing the SWF (Salt-Water-Flush) properly, you shouldn't be absorbing any of the sodium from that either. But like I say, that's just the first thing that comes to mind. It could also be some substance or other that is getting kicked out of our system but I don't know.
I am hoping someone has a more credible answer than the electrolyte thing because if I put that important balance out of whack, i won't be very happy with myself. I don't really think that's what it is though, because orange juice on its own wouldn't solve that and that's all I have had today, OJ and water.
I hope some others have something else to offer. Glad you're feeling better!
