I've been taking vitamin C for just over a week now (& Lugol's & companion supps). The past few days I've upped my dose to 5-6g. About 20 minutes after my usual dose this afternoon, I starting feeling very hot, panicky, jittery, light-headed & anxious, & I started sweating. Can anybody shed some light on why this happened? Detox reaction? Too high a dose of vitamin C?
