DO NOT RISK DRIVING!!!!!
I got the drops in at about 2pm, the effects did not wear off 100% until the next day! 2 hours after getting the drops I left Gatwick and took the train back to London to stay with a friend. I was unfamiliar with the route for one thing but I could not:
1. Dial my friend from my mobile cos I couldnt read the screen!
2. I could not read the tube maps on the train (I could only read the station names on the platforms)
3. I had to ask people for directions at all the stations.
It was extremely unnerving, If I had to drive home I would have been camped out in my car all night!
Funny when i look back on it though!
