I don't know about your tongue (I don't think its the diet), but wrt feeling high, well you went from taken nothing to taking everything, and that overnight. I don't know whether you need all these pills or not, I'm not a doctor. But if you do, perhaps introducing a new pill every couple of days would seem to be a good thing to do.

Personally, I take a good multi vitamin (without iron) and a calcium, potassium supplement.
