It's now 20 months since I touched a drop.
I can't honestly say I feel any better for it, and certainly didn't lose weight (although I'm one of those that only has to breathe in the vicinity of a Mars Bar to but a pound on. Always have been).
However, I'm sure my liver thanks me, and it's nice not to wake up feeling like scheisse after a big session, so definitely worth it.
On the subject of alcohol-free beers, I started off by drinking a few of them, but now I can't really be bothered and tend to drink more tea and coffee. In fact we're five weeks into a tour of France and I still have a coolbag half full of them in the moho's 'garage'. I think I've probably drunk five or six (mostly Beavertown Lazer Crush and Brooklyn Special Effects, both of which I really like, but I really have to be in the mood to even bother nowadays).
It really does get easier the longer you go on - but my daughters still ask if I dropped it for health reasons! No. Not really, but I suppose that's a genuine benefit - I hope...
