I Drink Alcohol, But After Drinking A Few Beers (3-6),

I drink alcohol, but after drinking a few beers (3-6), i want to eat something sweet, with milk of course. I'll take about two bites out of a donut, honey bun, piece of cake, brownie, candy, cereals, etc... A couple of drinks of milk, and immediately within 1 minute, my chest starts to hurt accompanied by pressure. Feeling it around my heart area, having me to panic that its my heart. Could it be the milk? The sweets?Or is it because the mixture of the beer?
