Is there anyone who has gained 50+ pounds during their pregnancy?

i feel horrible ive gained 71 pounds and im at 34 weeks! I still have 6 more weeks to go. Before i got pregnant i weighed 160 [i was still chunky but could hold it well] and now i weigh 231 pounds. Isnt that insane? im only 5'4". I had to go to the doctor's today and she was pretty upset with me. I dont blame her, but i dont care much at this point because my baby is very healthy :]. I gained 11 pounds over thanksgiving, i went to visit my dad and my brother and we went to fast food resturants almost every day and then we went to eat at my grandma and grandpa's house, so im not suprised i gained that much i ate like a pig. It was good accept for i can Never do that again lol.. Is there any healthy way for me to maintain my weight easier and not gain so much in the last 6 weeks? I let myself go for a while, but my baby is healthy so im not too upset. I just hate this extra weight, it feels like i have to lug myself around and its embarring. Has anyone else gained 50 pounds or more during pregnancy?
