I've been doing it this month, mainly due to work change and now have more time off.
As many off you know, I drive lorries for a living. Doing night shift also meant I don't drink Mon to Fri, but always had one on coming home on Sat morning (My Fri evening). And always on a Sat and Sun afternoon evening.
Not to a great extent, weekly total was usually a box of six bottles of Weston's strong cider, 4 cans of Tesco's own cheap cider and a glass or 2 of whisky.
New job is now 4 on 4 off, as the time off every week has doubled I could easily find myself drinking double that every 4 days if I'm not careful.
It's not going to be the full month though as I started on the 2nd and we will be going out next weekend to a show at Dawns work.
Not noticed a great difference apart from peeing more due to the amount of water I'm drinking instead
Ongoing I think I will limit the drinking to only when I'm off at the weekend and not on weeks where I'm off 4 days mid week.
