How do you guys prevent this? When I get it I could munch a 4 pack of Mars Bars in a minute. What should I eat or carry with me to stop this horrible feeling?
First I don't want to be alarmist or dispute what others have said but I recognise your "symptoms" and know they can have far-reaching consequences - a bucket full of jelly babies is not a good solution, nor a four pack of Mars bars. The following is my personal experience.
I'm 57, fit and healthy. I ride with a club and alone, 80-90 miles is not unusual. My wife, who has known me for 34 years, is a nurse, midwife, has other qualifications and is a health professional with 35 years experience. She clearly knows me very well, you will see the relevance in a moment.
I have had three grand mal seizures, at age 14, 24 and 57. On each occassion the sitaution has been identical - lack of sleep and very little to eat. Throughout my adult life I have had a tendency to become very slightly shaky (not discernible to others but I feel it) and sweaty if I don't eat correctly - I get 10-15 minutes warning of this and if I eat I'm fine very quickly. On the bike this manifests itself as a huge, almost overwhelming, desire for sugary products.
At 14 I had 5 years of tests every six months and nothing was found. At 24 I was a young man and simply ignored it. At 57, on the day when I suddenly felt crap, I shovelled down a load of jelly babies when I should have eaten. 45 minutes later, when I had just got home after driving I had a full blown fit. I was taken to hospital, told to stop driving immediately and two months later, after a ten minute consultation (!) with a neurologist, was diagnosed as epileptic.
Without going into all the detail both I and my wife are convinced this is low blood sugar but there is no way to argue with a consultant neurologist, especially when you want him to give you the OK to drive. The result of my last seizure is an epilepsy diagnosis ( better safe than sorry for the consultant), 12 months no driving and a lifetime of unwanted, probably unnecessary, drugs.
Eat regularly, properly, and carry food when on the bike and eat to prevent this feeling. I'm not trying to worry you or cause alarm but do feel I should pass on my own experience. Don't think to yourself I'm epileptic. Eating well is no hardship and can prevent a load of difficulties.
