Normal after the baby

To all my GD mommy's. I'm wondering, after you had your LO, how did your levels change. Did they drop dramatically or slowly easy off? Did you habe to continue taking insulin for awhile and then meds or diet control. I'm curious because I'm 28weeks (i know i stil have a ways to go) but ive been wondering what it will be like after i give birth. If i would have to keep taking shots or switch to meds...there are so many possibilities. All of which i dont know, Like if u have to take one or the other, did it effect you breastfeeding?
