Fairly sure he was dating Kathryn Rogers (the current Mrs. Limbaugh) at the time. So I'd say no.
Although the Viagra incident probably did have a negative effect on him. If nothing else, it could be seen as another warning shot by the left.
The only thing that bothered me about the viagra incident was that he said that he was getting a prescription in somebody else’s name to protect his privacy or some such. Must be nice. If doctors really do this, it seems that it would leave a lot of room for abuse. Maybe they won’t do it with narcotics and controlled substances.
