Caffeine on the road

Traveling in my car, I always take in too much caffeine. Coffee in the morning is only a start; later, to keep myself occupied in my car, I turn to diet sodas. Besides the issue I have with supporting the the anti-union soda companies, and in the case of Coke their death squad activities in Colombia, I was thinking that this much caffeine can't be good for my health. Of primary concern was possible dehydration. So, to find out more, I did a quick search on the Internet and I saw one of my favorite medical advice columns, Go Ask Alice. After reading the column, I'm definitely going to try to cut down today in my car, after my first coffee. One symptom in drinking so much caffeine is being simultaneously tired and not being able to sleep, a problem that I have been experiencing this summer. Strangely, I wake up early in the morning, wanting to get up, but also tired after only getting 5 or 6 hours of sleep. I didn't think that caffeine might be the issue!
