I am at 5 weeks also and I feel the exact same way. I thought it was supposed to be the other way around! I esp. do not want to eat meat, veggies and other dry foods like pretzels. I am trying to squeeze in those foods when I can bare it, and focusing on wet foods like canned fruit and oranges. For some reason they go down better. Maybe its the sweet taste.
I also love grilled cheese right now. I am eating them everyday and since it is not a junk food I am just going to go with it. At least its food.
