Exactly as Judy wrote. Also, I think it's too simplistic to say your seizures were caused by consuming too much beer. Yes, beer itself has lots of carbs. Beer also has alcohol (although not as much as wine or liquor) and can cause other conditions when consumed heavily over a period of time: weight gain, gout, kidney and liver problems to name a few.
There are lots of data available on the Internet about diabetic seizures and lots of information about medical problems caused by alcohol overindulgence.
If you would like guidance about diet, lifestyle and general diabetes information, please post again and we will be happy to answer your questions as best we can.
