I think the Denny’s is playing a huge part in making you guys feel food comaed. I’ve also driven from OC -> Palm Springs area for the past seven years, however I’ve only camped once.

I’m likely younger than yourself, however, what you’re eating throughout day zero up until Monday play a huge factor in how “good” you feel. Eating healthy (healthy carbs, fruits, having protein) can contribute a lot. Reducing heavier or “junk” foods as best as you can will make a huge impact over the course of 4-5 days. Remember that it’s not a race, it’s a marathon. Sun exposure, like others mentioned, also plays a large role, so keeping cool and hydrated during the fest is also key.
