Not a guy but am an occasional beer drinker so thought I'd pipe in. I didn't drink carbonated drinks of any sort when losing but now in maintenance, my band isn't that tight and I can have a beer or two without too many issues. More than that and the bubbles make me feel really full and uncomfortable. Despite this, I have been known to sometimes push through this to have more than two (I recall a particularly messy St Paddy's day this year... lol)
There is absolutely nothing as great tasting as a beer on a stinking hot day. And yes, I think drinking it out of glass and not the bottle definitely helps as the carbonation dissipates a little as you pour it out.
