Here are some words of wisdom: make sure to drink enough water to stay hydrated but some of the recommended 8 daily glasses comes from the food you eat. So those 8 can be small glasses.
About the car, some things to check are the alternator pulley. Remove the serpentine belt (look in the fAQ for some tips) and use a wood stick to hold the fan inside the alternator. The pulley should only rotate 1 way. If not the clutch inside is bad. Does turning on the electrical equipment raise engine rpm? Manual or DSG?
