"When a legislature undertakes to proscribe the exercise of a citizen's
constitutional rights it acts lawlessly and the citizen can take matters into
his own hands and proceed on the basis that such a law is no law at all."
- Justice William O. Douglas

Itch where? Cant say as I have noticed any difference. Then again I also
take a drug for gastric reflux that causes me to break out in skin lesions
on the arms....
