Stomach flu or gastroenteritis infection signs and symptoms include nausea, vomiting, and diarrhea that lasts for about 7-14 days. The stomach flu is spread from person to person, usually via fecal to oral route from poor hand-washing or hygiene techniques.

I believe beta blockers work immediately. They are for your heart rate and blood pressure. Your BP may shoot up when you're real anxious, that's why I have to take one. But, they do not stop or prevent anxiety-they just keep your blood pressure in check so it doesn't shoot up when you are very anxious. Hope this.
