Re"孕前我很鄙视各种垃圾饮料,怀孕后彻底变了个人。喝白开水都觉得恶心,要喝气 泡水,吃薯片汉堡炸薯条". I was the same. My husband couldn't understand why I chose to eat unhealthy when I got pregnant. I told him it was NOT my choice. It's the only way I could keep food down. Even when I threw up, it felt better to throw up food than the stomach acid. My OB said it's fine and normal. Now I'm in my third trimester and things seem to have been back to almost normal.
