Hi Bunnybabes
1000 - depends on what you drink. If you have 5 pints of lager or beer - you've blown your 1000 plus what about the food you get on the way home cos you are so hungry!!!
So afaik - stick to spirits - don't get a kebab on the way home and drink lots of water when you get in!!
The latter not for calories - but to stop your hangover LOL.
