Red freckle-like dots after drinking

I find that sometimes after drinking (usually when I drink a bit more than I should) my face will break out all over in tiny red dots the morning after. They aren't raised or swollen and they don't hurt. It usually takes 2-3 days for them to fade completely. I'm wondering if I have an allergy I'm not aware of. The obvious solution is to drink less, I know. But still....curiosity. Thanks!

i find that when you throw up you get red freckle like dots around your eyes and cheeks so if you regularly throw up when you drink then that is probably why. the red dots are from the heaves. hope this helps
