I too suffer from the same symptoms all be it with minor diffrences
Numbness , blurred/split vision , dry mouth , frequenter urination and reduced hunger mine followed a viral infection and i too have no answers i have looked around to see if your symptoms match any common neuro problems and came up with nothing sorry, but that doesn't mean it cant be found !
Best of luck and if you need to complain im also annoyed.

Good luck
