I am 18 years old, and I am a freshman at UC Berkeley. I moved in to the dorms here on campus, and at first I was loving the buffet style dining halls we get to eat in. Now, I am experiencing headaches after every meal. The headaches will often occur before I have even finished eating, causing me to lose my appetite. This only happens when I eat food on campus, but I'm not sure what it could be in the campus' food that would cause this. Is there any way of avoiding this? I have to eat on campus because this is where my meal points are to be used, but headaches three times a day is very stressful.
