Burst of energy after having baby???

Ok, so I gave birth a week ago to my baby boy and was sent home on Monday morning.   On Tuesday,  I kind of layed around and took it easy (had a 3rd degree tear so don't want to overdo it).   But on Wednesday and since then, I have all this energy and am constantly running around doing things at the house.   I take a rest here and there for 10 minutes, but am thrilled with all this energy I have.   I was so tired during my entire pregnancy and was constantly laying around and not able to do very much.   I was frustrated because I wanted to clean my house, run errands, and just a bunch of stuff and was just too tired to get out and do it or get up and do it.

So it's almost like I feel antsy and like I have to be doing something or I'll go crazy!  LOL   I love all this newfound energy I have and wonder if it'll die down once I am used to not being pregnant and the newness wears off.  I even went to Target today for an hour  with baby and walked around shopping- I feel GREAT!! 

I do remember I had this type of energy once I lost all the weight and just before I got pregnant though.   Everyone says how good I look and are shocked to see me at the store or outside.   But I feel great!!  And I'm getting an average of 4-5 hrs of sleep per night, so I'm not very tired (which is good for baby being a week old I think for me to get that much sleep).   I don't nap during the day because it makes me not tired till way late at night, so I just rest here and there throughout the day if I need to. 

Anyone else feel this way?????
