You are going to gain faster with your 2nd than your first, so please don't compare because every pregnancy is vastly different from the next. And I'll tell you, I've known several very healthy people who only wanted junk when pregnant. If veggies or something healthy makes you feel ill, how is that good for you? Just try to venture out and find other things that are satisfying. Once place I loved to go pregnant was Boston Market. They had the BEST comfort food. Creamed spinach is loaded in fat but at least I was eating spinach!
I gained 23 with my 1st, craved health food the whole time and fast food repulsed me. I gained 58 with my 2nd, craved sweets and anything deep fried. You just don't know what's going to happen until it does with pregnancy. Try to fit in healthy food when you can but again, if it makes you sick to eat it, you're accomplishing nothing. Don't worry so much, honestly. You will gain quicker with the 2nd and look much more pregnant sooner too. It's natural for a us. Just try to relax about it. I honestly can say I should have bought stock in Haagen Daz because of the enormous amount of it I ate. I made them a TON of money. >: )
