I'd go with the dehydration rather than the salt imbalance.
I'd be surprised that you actually sweat that much on an average class night to cause potential salt imbalance (especially at this time of year). My understanding is that salt imbalance doesn't cause headaches anyway; I spent a summer working out on site in Dubai (construction of a power station next to the sea), and I used to sweat loads, and have to drink loads. Your body gets most of the salt it needs from normal food (assuming that you are eating a balanced diet); I was having to drink over 6 litres of water a day to stay hydrated whilst out on site, but got all the salts I needed to replace lost lost via sweat from my normal diet.
My understanding of the salts in energy drinks are that for typical sportspeople, the dissolved salts in sports drinks are to do with water being absorbed more quickly rather than actually replacing lost salts. I'm not an elite athlete so am happy to be corrected by a sports scientist, but none of my colleagues out on site needed to take salt tablets when sweating much larger quantities that an average Ceroc night; it was a very hot (48 degrees) and humid environment.
Are any other factors involved; do you eat or sleep differently on dancing nights?
The previous comment about loud music is a possibility to consider as well?
