Alcohol never affects you in any beneficial way at anytime or if your system does not tolerate it well. This is just plain common sense. You should be asking about some of the wondefull things you should be eating after the fast to maintain the benefits gained yet you ask if it's OK to drink a "known" toxic substance.
I am not teatotaler by any stretch of the imagination. I do enjoy my brewskis occasionally but I do know and accept that it ain't the best thing for me. It's about a once a month and sometimes longer thing for me cept if I'm on vacation then all bets are off ;+D but i do make sure I drink lots and lots of water. Since I am in good health and have been on the cleansing trail for over 2 years now and I do take care of bidnez the rest of the time I don't worry about it and just enjoy it.
I will tell you this after my most recent 21 day Master-Cleanse
about 5 or 6 days after, I was hanging with my homies and they had some of them fancy schmansy brewskis and boys being boys I indulged. I was very conciencious though and for every beer I drank I would refill the bottle twice with water and drink that after. I only drank 4 beers over a 3 or 4 hr period and I got zonkered. The next day I couldn't find one of the sandals I had worn the night before and found it later that day in my front yard..............
