I think it's the headache/migrane. W/ regular run of the mill headaches if they are bad enough I feel sick sometimes. I agree that just taking it easy, eating light, especially if your'e hungry since hunger can make a headache worse. Try to sip on water as much as you can too, if it's been especially hot you may just need more fluids than you have been getting. I hope you feel better soon! Oh don't laugh at me but i read an article by a doctor a while back who mentioned a way that worked on many of his patients to get rid of a headache and I've done it and it's worked! You take a banana peel(s) and put one section of the peel across your forehead (the inside part that touches the part of banana you eat agains your skin) and do the same to the back of your neck. Keep it on (preferably while lying down or sitting) for about half an hour. I don't know if it's psychologically works or if it really physically works but it has for me! good luck!
