Though my mom's lasagna was wonderful, things don't taste the same to me anymore and it sucks! I'm even hating the taste of water. I'm sure I'm dehydrated by now but I makes me cringe to drink anything and I can only eat exactly what I have a taste for! Anyone else like this?! It makes me sad cause I'm not even 8 weeks in!
