Last year after an intense start to the year and a battle with mild depression I took the choice to stop eating meat and drinking alcohol. The results to say the least where life changing.
Not only was I in better shape and looking much much healthier, my mind started to think on a different level. I became more intuitive and aware of my surrounding. Like finally I had plug myself into life. No longer did the weekend consist of drinking in the pub followed by eating a shit load of meat and my body being put under huge pressure. I felt light and free and clear headed.
I would encourage anyone to give it a try for at least a month. It is tough but once you feel the difference. You will start to see the reasons for giving up outweigh the reason for continuing.
