I forgot to post the info I have on "emotional lability" (or Pseudobulbar affect (PBA)) that often occurs with MS:

My mom had schizophrenia (not MS tho'), and I've witnessed "mild" through to "severe" mental illness. I've also seen what the wrong chemicals can DO to a person, so I think it is very important you are properly evaluated!!

Bi-polar is more common in MS then the general population, but if I recall correctly, not THAT much more common. I think something like 1% of the general population has bi-polar, and 2% of people with MS have it. MANY of us have emotional lability though, and it manifests itself somewhat similar to bi-polar . . . the difference really is how "extreme" the behavior is.

Please get a proper evaluation before starting on a drug such as lithium.
