Pouring your beer with as little foam as possible isn't actually the right way to do it.  It makes you more bloated, because there's more CO2 still trapped in the liquid.  In other words, you'll feel a lot less bloated if you let some of the bubbles pop BEFORE you drink it. It's especially important if you're also EATING, because when the food hits your stomach, it reacts with the beer and releases even more CO2.  So then you end up even more bloated.  So ideally, your glass should be about two-thirds liquid, and one-third foam.
