Hi,
After 2.5 years, I recently left a nurse consulting job at a pharmaceutical company. Overall, it was very positive.
Pros: Not very strenuous, still get to communicate with patients, you can only take one call at a time as opposed to 6-7 patients at a time!
Cons: You're tied to a phone and can't move around much, you need strong phone assessment and call handeling skills (difficult to know whats going on over the phone), all of my calls were recorded and audited.
