I stumbled across this site the other day and immediately bought Pepcid AC max.  Took two pills (40 mg total), waited 45 minutes, and had a glass of wine, which ordinarily would tomato-ize me.  I had the rapid heartbeat  that usually signals redness, and I felt warm and flushed.  But I looked in the mirror and I looked normal!  I didn't look like I was standing under an infrared bulb; it was all good.

I didn't get shitfaced drunk and only had a glass of wine, so I don't know how well it would work at, say, a night out with my K-town friends.  But the initial experiment was great.
