I started feeling nauseous and gassy around 3 and a half hours ago. Since then, the nausea has gotten worse and I feel like my stomach is a little acidy. I forced myself to eat some crackers but it really didnt help. I feel hungry but very nauseous at the same time. I'm so scared I'm going to throw up. I've also taken about 4 Peptos in the past 4 hours and it hasn't helped.
