Geometric Hangover Progression

Is it just me or do hangovers often actually get worse as the day goes on? One time we were camping and I woke up feeling a lttle tired, slight headache, had some breakfast, was basically fine. Then I started feeling worse and worse, by noon I had puked up everything I ate and was dry heaving on the side of the road (on hte return trip from camping). I have had things like this happen relatively often. I drink a fair amount, wake up ok, but as the day goes by it is like the hangover is on a timed delay. Anyone know anything about this? Is it just my alcoholic metabolism?

Just a well informed WAG, but I’d say it is because when you wake up you still have a lot of alcohol in your system. As the day progresses and your body rids itself of toxins (you become sober) you get sicker and sicker.
