I've never driven drunk directly (by that I mean the same night), but I have driven home the morning after a drinking session. I had heard about how much alcohol stays in your system afterwards, but I don't think I ever really realised quite how much. That's entirely my own fault of course, for never having looked this up!
As much as this is wrong (if you're over the limit you're over the limit, end of), I do (for some reason) see it differently. I'm struggling to think why, but I do. I suspect seeing these stats will change my opinion of driving the morning after but - and I'm not just saying this - I'm blessed with being one of those people who sobers up (not just not getting a hangover) quickly. Now obviously, how you feel doesn't dictate whether you're over the limit or not, but as everyone processes alcohol differently you must have to use some sort of personal measure. How much more can you do than that, except breathalyzing yourself every morning? :?
Incidentally, one of my old school friends has a big farm on the outskirts of Bristol and every year we go up there for a massive piss-up. There's an insane amount of booze, massive fires, he has a big pool with roofs and stuff to jump from, quadbikes, motorbikes, bangers like... the works. I've driven one of his bangers around on his top field when I've been completely hammered and it's actually terrifying. I must have been around as drunk as that guy that Jordan stopped the other day, but even in a completely danger-free (with regards to hurting someone) environment it really did shock me how little control I had over the car. I guess that's been the biggest thing that's made me realise it's really REALLY stupid to go anywhere near a car when you're drunk.
So yeah, I'm sure I've done it, but never on purpose. I have no tolerance for people who do it 'actively', and what I've done is wrong (if I've been over the limit), and maybe I'll think differently about it now. Then again, when I'm at Uni this is never an issue and when I'm at home I'm nearly always picked up and dropped off (same night or morning after) so...
