I used naproxen (sold as Aleve here in Canada) for the afterpains last time, and it was GREAT! I honestly hardly felt them, and that was baby #6. With the others I was on acetaminophen and ibuprofen extra strength taken together, and still was rocking and breathing and moaning through some of the pains, especially when nursing. Ugh. I highly recommend the naproxen! My midwives told me to increase the dose from what is on the bottle (instead of one every 12hr, take 2 to start, and then 1 every 8hr.) I only needed them for about 48hr, and then acetaminophen on it's own was fine for another day or so, and then everything was OK.
