I had a really bad reaction to some pain meds I was prescribed, and I've been puking for 6-7 hours now, literally there looks to be over a gallon of vomit in my trash can alone, and that's not the only place I puked. I tried some canada dry ginger ale, until I found out there's no fucking ginger in it. Now I'm straight water and ice cubes. This is my fourth attempt to keep something down, I'm scared I'm moderately to severely dehydrated. at what point should I be going to the emergency room
