So I've been reading this board for a few weeks and decided to buy some Pepcid and start experimenting with the so called Flush. 

Experiment #1
Took 2 Pepcid ACs 20mg each and did not eat anything.  Took pills about 30 mins before drinking.  Drank 2 Blue Moons and was feeling good.  Normally when I drink Blue Moon, I get red REALLY fast but this time, I was barely red and my face wasn't burning up.

Experiment #2
Took 3 Pepcid ACs 20mg each and ate some food before taking the tablets.  Took the pills about 1 hour before I started drinking.  I had 2 Captain N Cokes, 1 Magarita, and 3 Miller Lites.  I was definitely buzz but I was not red at all.  I was a little pink but nothing like I normally would get! 

Woke up both mornings feeling just fine.  No side effects from it.

So far, the tablets seems to work extremely well.  Will post more results as soon as I can test it
