Off the top of my head, I would say the beer should not have caused the feeling you described and #1 and #2 should not have, either. I know Dr. Schulze is not AGAINST drinking beer, but he doesn't encourage it, either. He suggests that even mixing the SUPERFOOD with beer is better than nothing......
Maybe the intestinal #1 and #2 are cleaning out your colon and some toxins were released while drinking the beer causing the problem you described. Please keep in mind I am only guessing and someone who is a lot smarter than I am may be able to give you a better answer. The #1 cleans out out completely, so it might have been drinking beer on an empty stomach?
Anyway, keep on the the #1 and #2. Most people are able to take it and reap wonderful benefits! Good luck and good health!
