I wouldn't risk it either. It's just not worth it. Abi and I are around the same size. My friend's husband is a police officer, worked in traffic for a while and told us that I would probably be over the limit if it was checked after a glass whereas he (big guy, over 6 foot and about 15 stone) would probably be okay up to about 3. Because people like Abi and myself are small it has more of an effect. I know that I'm fine after 3 glasses of wine (as in feeling fine obviously NOT fine to drive!) but it's always the 4th glass when I start getting very chatty and giggly.Oh right, I wouldn’t dream of driving even with one glass of wine but that’s just me.
Then again that might be all bollox in Abi's case because she's probably built up one hell of a tolerance at this stage!
