People only believe government/medical guidelines when it suits themselves.
I rarely drink, if I drink alcohol once a month it surprising but I definitely go over my daily guideline when I do. I have sole charge of my children so the ifs and buts aren't really an issue for me. Ive never drunk at home alone, its the slippery slope to loserville.
Whoever it was who has the mate who drink drives regularly, I am stunned! I wouldn't be friends with someone who did that, with any luck it will only be himself he injures when his luck runs out.
