Units, Dry January and a no-drive warning that stays serious
UK guidance is not regularly drinking more than 14 units a week. These tools count units and costs. They never say you are safe to drive.
Check drinks, then the habit
Start with weekly units, then a dry-month tracker or a quit-cost tool if nicotine is in the mix.
