Soo like a month or 2 ago I felt really full and I don't remember being nauseous at all or having stomach pains or anything but I had this strong urge to gag and to surpress it I was sipping on 3 different drinks sprite ginger ale and water but ended up gagging really hard 3 times in a row. Now is that what retching/dry heaving is or what it feels like??? And does that feeling always precede vomiting??? I hope not cause it was terrible. In don't remember feeling like anything was coming up or felt like it was coming up just gagging.
