I find a chocolate vape goes well with beer, not a sweet chocolate, something like Vapor God's Choc Hazlenut or deejStuff's Choc Almond Ecstasy.
Lowering your nic level while drinking is a good idea if you can do it, but I really need a throat hit when I'm having a beer. If I'm ever going to have a traditional cigarette again, it will be because of not getting a throat hit when I've had a few (too many) beers.
