Giving up alcohol was easy for me, I used to drink, I used to get hammered fairly regularly and enjoyed beer and wine, but I decided to knock it on the head and stopped drinking. TBH, I don't miss it at all, there is no conscious effort to avoid it these days, I just much prefer to drink coffee or soft drinks when out and about. Now giving up meat for a period of time, well that was a hell of a hardship and I just couldn't hold out, I need my burgers and sausages! I wouldn't bother even trying to give up M&S Chocolate Milkshake!
