That's so funny. I've never been high, unless you count one unpleasant afternoon where I must have gotten a contact high from the kid I sat next to in astronomy class...the kid who smoked pot behind the school after lunch. That was one of the worst headaches I've ever had. It's hilarious to me to think that that fog of sleep deprivation is like a high. People do that on purpose?!?! lol.
With DD we did not have stairs and I cooked dinner the next day! It was easy. Depends on the birth you have too. I had her drug free and it was an easy birth so I felt great. I know many women who get epidurals etc have a harder recovery. C-section obviously takes time to heal as well.
A new baby nurses like very 30 mins though and it's hard to plan anything and you are in SUCH a sleep haze you feel like you are high as a kite.
And, about the guts falling out. After my first was born, the one where I started doing everything right away, I did feel things falling inside of me, literally falling. My midwfie after my second said that it was my organs going back into place and a sure sign I was doing too much. I forgot about that. My second, though, I ran up the stairs at the hospital the afternoon after he was born, no big deal, and continued to have a pretty busy life, with no ill effect, and no falling feelings insdie. (I did have anemia, though, and would have severe dizzy spells and extreme exhaustion, and he was a screamer and it was HARD.) But my insides were intact. :)
