Rmh101, going back to your original post, you say you have only had your licence 4 months.
The new drivers act provides for people in their first 2 years to have to retake their test if they get 6 points or more. The good news is that this doesn’t apply because drink driving carries a straight ban and no points.
the bad news is that the magistrates could decide to order you to retake your test because you have only just passed and now committed a serious offence. It is a lottery as to if they decide to do this or not, some courts do it more often than others but you should be aware of that possibility.
Also you say this took place over 5-6 hours. This makes the spiked drinks even less credible because it means that your soft drinks would have to be spiked with up to 12 units, so 300ml of vodka. That is a hell of a lot to not notice!
You say you “felt so unwell, I just wanted to get home.” With hindsight you did not feel unwell, you were fairly drunk. As you had experienced his before, the court will conclude that you should have realised you were unfit to drive.
I am not seeking to be harsh with you, just pointing out the reality of your case.
