...Are so low it means they have to be virtually ignored if you wish to drink alcohol.
For women it's 2-3 units in a day. Which is a glass of wine. Therefore if you have 2 glasses of wine with dinner, even if you are totally sober, you are technically binge drinking with all the stigma and worry that attaches itself to that.
The number of units decided upon as safe is also completely arbitrary and not based on any actual evidence.
These two things together surely mean they are likely to be ignored if you like a drink as they simply cannot be comfortably adhered to.
AIBU to think they should make them more workable to make them more effective?
