migraine
"Migraines I understand, and I used to take Excedrine migraine decades ago before my kids were born and it worked...that being said, I don't know what they did to these pills, but they took an extreme toll on me after just two more than 12 hours apart. 
I had multiple anxiety/panic attacks, shortness of breath (may have been related to the attacks), a feeling of what I can only describe as Deja vu constantly for hours that was debilitating,  fatigue, nausea and more. I have no bad medical history of any kind, no depression, no mental issues, never had an anxiety/panic attack, sleep and eat well, and I've never used any illegal drugs or even prescription drugs other than the birth control I have been known for years."
