I've purchased several of those beefy crunchy burrito throughout Fountain Valley and Huntington Beach, CA - I notice I was having this extremely horrible headaches - I'm 54 years of age and I have never experienced headaches or migraines - so I tried to think what I had been doing different since the onset of these excruciating headaches. The new beefy burrito - so I stopped consuming them for 4 - 5 days. Stopped into a Taco Bell - ordered the crunchy burrito and within a few hours - my headache had returned. I also noticed I actually craved this item. There must be some chemical they use that actually makes me crave them - and in turn gives me an excruciating headache. I will no longer be eating at Taco Bell..
