I think it is actually a positive sign when the body reacts strongly to alcoholic drinks. After all, it shows that your body still recognizes the substance as toxic (which it is, despite the fact that it is legalized). Alcoholics need to drink much much more in order to feel sick - their bodies are used to it. I think to stop drinking alcohol it needs more than changing to smoothies. It is rooted deeply in the body and mind of the addicted.
One cannot think well, love well, sleep well, if one has not dined well.
