I'm 8 weeks today, with my first US scheduled for tomorrow. I was told to drink 32oz of water one hour before my appointment and hold my urine. My problem is, I feel sick all day, every day and can hardly keep down 32oz of water in a day, let alone within an hour. I'm pretty sure I won't be able to keep it down. I'm trying not to stress but, I'm stressing anyway, and that makes me feel even more sick.

Any advice for keeping it down? Will they still give me the US if I don't drink the 32oz?
