Bro, this field is a freaking mess right now.
A few years back they changed s#!t up and stopped all the "free lunches, breakfasts and tickets" that reps would drop off all the time at the doctors office. Also, sounds like your dude friend is not a dudette...so that will not help one bit. That field is female, big time.
I have a good friend and his brother and brothers wife both were in the field. His brother lost his job and has tried for the last 10 years to get back in with a sweet company like he was before, company car, 20 hours a week, lots of golf and making bank, no such luck. His (now ex wife) is still working with that company.
I also have a friend (girl) that does med supply sales and she loves it, travels a decent amount but not a ton and does really well.
But from everything I have been told is that it is much harder to get into and to stay in the field now than it was in the past.
