I often experience my annoying "heartsymptoms" at night after eating a good meal and drinking maybe 1/2 to 1/1 bottle of wine.
This night, for instance: I was just fine when I went to bed (5 glasses of wine), but after 2 hours I woke up, my hearting beating really hard, and with an uncomfy feeling in the breast region!
The pulse was only slightly elevated and there were no skipped beats or extrasystoles to be felt.

Can digesting food in stomach and intestines/processing alcohol in liver make these organs in need for more blood, so that the heart would beat extra hard to get the volumes out where needed?
When I get these "spells" I can't fall asleep again, it feels as if (theory in my little head ...) my tired body wants to slow down the heart to fall asleep, but the heart responses to the slower pulse by beating harder to get some blood out to "work".
Could that be so?

Of course I know the cure: Only 2 glasses of wine ...
