Numbness in mouth symptoms and conditions

Hi and please feel free to email me. I was on Lipitor for quite a while (20mg)without any issues. Due to insurance etc I was switched to 40mg of simvastatin---with in a short time i noticed i was waking nearly every morning with a mouth full of junk requiring a deep throat clearing. Then a low level sore throat that persisted for more than two weeks. I went to my doc who agreed that it may be related (though I think she doubted it) and had me stop. Now i have been off for 5 days and still my throat is sore (though not sore to swallow) and mouth generally feels "messed up".

If any of you have had any sore throat experiences etc please let me know. Also how long did your side effects last once you came off the drug?
