Hi, ladies. I'd love to join you!

Just a quick intro:
I gained back 40 lbs in 2 months (yes, two!) after having lost 68 with atkins, never could lose it with anything again (granted, I didn't try atkins again). I did SBD, CAD/CALP, blahblahblah.

Now I'm pregnant with #2 (due 02/21 so I'm almost 16 wks) and am still breastfeeding my 19 month old big boy. I'm thinking of doing LC during this pregnancy. Since I'm 5'1" and started at 168, I figure I can gain about 20 lbs and be alright. I'd prefer not to gain anything but we all know how that is!

I know I'm eating way too much sugar. Last pg I ate anything; I was within 5 points of not passing my GTT. I don't want extra weight gain.
I gained 36 lbs with my son. Granted, I lost all the preggo weight but never lost anything else. Sigh.

So how do you guys handle it? The only things I seem to be craving are dairy and fruit.
