Pickles and Mustard

Okay, I am allergic to vinegar, and subsequently cannot eat pickles or mustard. I never have liked them either, the taste or the smell, so really this was not a big sacrifice.
However, lately, I keep wishing I had a cheesburger with some pickles and mustard on it. I can't eat them however, so I just sit here, thinking about mustard and a crunchy pickle, wishing I had some to enjoy.
Every BallPark frank commercial drives me to drool too--I sit here thinking about how tasty a hotdog would be with some onions and mustard on it. I usually can't stand hot dogs. And onions and mustard? Sick. However, right now, nothing sounds better to me.
McDonalds always sounds and tastes so very delicious. I have tried to only eat there once a week however, so as to not cause my body to go into liver failure. However, if it weren't such a bad thing, I'd be eating a Big Mac every single day.
Oreos are the other thing I can't get enough of. I have never disliked Oreos, but I could eat a couple, and be satisfied for a year. Now, I want to eat them all the time- I don't, but I'd like to.
Finally, homemade lasagna is quite possibly the best thing in the world. I can't get enough of it. I make it with fat free cottage cheese, lean ground turkey or beef, and wheat-free pasta, so as to try to cut down on the fat and cholesterol...but it is still oh so good.
This does not bode well for my child's future...I blame my husband and is propensity to eat sweets and meat in large quantities.
My sister couldn't get enough fruit when she was pregnant, but I just want the junk food. I'm trying desperatley to be healthy, eating at least one big serving of pears (one of the only fruits I can eat) every day.
I don't really want to gain 100 pounds with this child, so I'm trying to be very dilligent about what I eat, however, would some one please give me a ball park frank with some pickles and mustard on it?!?
