Dizzy. Can't stand up for long. Nauseous. Vomiting. And a nose bleed last time I vomited. I went to bed hungry last night. Do you think that's it? .. I didn't eat a snack because I Have to take Zantac before meals or I vomit. I've found when I eat a bedtime snack I just get sick. So I ignored it and went to bed hungry.
