Pfizer Sales Rep Job - Work/Life Balance?

Thinking of applying to Pfizer for a sales rep job. So tell me honestly....after working as a Pfizer rep during the day, how much "work" needs to be done at night???? Like programs, paperwork at night?

How many dinner programs a month?

And how much paperwork at home every night? Like business plans, expense reports, etc etc.

Thanks.
