"i wish i had read about this pill before taking it. i was on minestrin for two years and loved it. cvs switched me to mibelas, and i experienced terrible headaches and extreme shortness of breathe to the point i thought i was going to choke to death. it took me awhile to figure out it was the mibelas, but when i did, i stopped taking it, and i never felt better. i had constant headaches for the 2 months i was taking it, and severe anxiety. i stopped going to class and literally thought i was losing my mind. it is not worth the price difference between minestrin and mibelas. this product should not even be sold."
