that's barely enough! Good grief man, you had me convinced you were one step away from a starring role in a Hogarth engraving!Too much and increasing, which is why I stopped. On average 2-3 glasses wine most nights. No beer or spirits.
I found as I get older (I'm 55) even a couple of glasses would leave me feeling sluggish next day.
So now I can put much more effort into my rides which I think has also helped with the weight loss.
I genuinely don't think that if I stopped drinking (my intake is a little less modest than your own) that I would lose two or three pounds in total, never mind a week. And the risks of sobriety are considerable!
(Actually I gave up drink for six months in 2003 and lost about half a stone, but I was also doing 250 miles a week at a tad under Mach 1)
