Bad lifestyle choices, like poor nutritional habits, smoking, substance
abuse which includes
alcohol-sake is a very powerful alcoholic drink!-
deplete even more energy from the body.
My guess is that you have a candida infection, and that your alcohol is feeding the candida, being one of it's favourite sources of energy for growth.
If you feel the need to consume alcohol, it's not just your brain that wants it, it's the candida also that wants it!
