SO I neve drink while drunk because it makes you too messy. But I've driven while on amphetamine and I drive very well, also have driven few times while on GBL, also lots of time when on benzos and for many year I droved while doing some good old poppy tea, I didn't took so much that I nod only to get my mental state normal (positive about live). Scariest thing was what when I was on high does of tramadol and I nodded constantly, but I frocer my eyes to open. Also sriven when blazed on cannabis. I see GBl and alcohol is most dangerous drugs to use while driving.
