With certain things I will jump right to the strongest thing in my arsenal. With my first, I had after pains, for the most part, I managed it without medication. With my second, it was as bad as the labour. I took about 1000mg of Advil and curled up in bed fetal position for a few hours. I wasn't going through labour twice in two days. lol I've only given birth in hospitals, but they bring you the Tylenol and Advil right after delivery and tell you to switch every two hours if needed. First child, I didn't think that was necessary, second child, I saw the logic.
Really, I agree with the PP who mentioned that you're tired, your body has already been through the ringer, even moreso if you've given birth without pain meds. In my way of thinking, I've been strong, I've delivered this baby, I have to rest as much as possible to make milk and feed around the clock, I'm going to be wiping noses, cleaning wounds, making cookies, helping with projects and doing laundry for the next 18 years or so, I'm giving myself this pain relief. *G*
