Pump and Dump?

It's been a year since I've had a drink and a nice cold cider would be so refreshing on these warm spring days! I've read so many mixed opinions about pumping and dumping. Is it necessary? What do you do? What has your midwife/pediatrician told you? I exclusively breastfeed and so do every 3 hours during the day and 3-5 hours at night with my 8 week old.

Thanks
