I have had the same issue for about a year now. It is to the point that I wake up the next day and think that I have the stomach flu because I am constantly throwing up. It is a relief to know I am not the only person dealing with this. The only thing that somewhat gets me through being sick is drinking 7up or ginger ale . For some reason this stays down better than drinking water. I still might throw it up but it stays down much longer.  I very rarely drink pop but I will do anything to feel better during these horrible hangovers.
