Dramatic increase in weight gain

Mel
I am quite tall at 170cm but I weighed 65kg before pregnancy! 
I'm now 21.3 wk preg with 2 babies and I weigh 83kg! That's 18kg already! I think I am going to put on 30kg or more once I reach almost full term :/ (hope not though)
It does make me abit depressed to think how much hard work I'm going to have to spend trying to get rid of my new love handles and all that stuff I've developed so far but I can't be any more proud that this body is changing and God does miracles with what's growing inside of us..
I wonder how much weight everyone else has put so far?
