For fun I did an estimate on how many times I've pumped since I went back to work, just counting the weekdays, and I came up with at least 400 pump sessions (5 times a day, Mon-Fri). And that doesnt even count the weekends. That's 400 times I"ve hooked myself up to my trusty sidekick, my Medela PIS! Good lord! Just thought it was amusing. Imagine how many ounces that comes out to, LOL!
