Same, but I suspect it also has to do with changes in my heart rate due to lower quality blood at the time.
Now that I wear an HR monitoring watch 24/7, I can easily spot nights I drank too much. Instead of 62 resting heart rate, I'll have 75-85. And if you think about it, normally when you have somewhat elevated heart rate, something active or interesting is going on (which provides distraction). But if you're just chilling, but intoxicated, you may be more likely to notice the increased blood pressure.
