If you are going to want to have a glass of wine with friends then you may want to put off the cleanse until you are mentally ready for it.
The purpose is to clean out all the crap you have been putting in your body. While a little red wine is good, it does have things in it that may work against you while you cleanse, i.e. sugar, preservatives ...
I am a social butterfly...told all my freinds what my goal was and that helped them help me.
And since I have been off the cleanse 1 week I have absolutely no desire for alcohol what-so-ever. I don't miss it.
It's about mind over matter...willpower and discipline.
