Pyridostigmine
"I have Cervical Dystonia in the right side of my face and my eye and  Mouth droop.  I have only been on this medication for 4 days and can already see small changes.  If it works like this, I'll take it forever.  I used to have such a pretty smile and now it only smiles on the left...its awful.  My nuroligist was giving me mylobloc  so now we'll try this!!  No side effects so far. Linda in Fl."
