Good luck tigwig
I am one of these people who take from Jan 2 off to Feb 2 (this year tomorrow until 03.02 cos of the holiday).
They say it does no good medically - well sorry I disagree as I find as I "detox" I shed some 8 to 10 pounds over the 4,5 weeks. I also come back slowly onto drinking (which is mainly wine anyway).
In addition, I often take an additional 3 weeks in August.....
I do feel better for it and no I do not crave the booze, or go through itches etc ......this year may well diet a bit too and cut back on the bacon and sausages etc, though one shouldn't really lose more than 3lbs a week - risks to gall bladder etc with accelerated dieting. The food diet does lead to one craving though - for cheese and I use that as a little "reward" for myself. As to the drink part, no such rewards - the replacement being water or the occasional unsweetened fruit juice.
