Yes mrsD, it is the exact supplement that I used. I also forgot to mention that I used the supplement before the first incident(day before), and the only symptom I had was a severely twitching pec muscle. It probably would have been smart if I would have stopped there. Well, the second time I took it only 20 min elapsed in my workout when the dizziness, twitching muscles all over, brain fog, confusion, heart palpitations,shortness of breathe, extreme fatigue, pulsating head ache, and jaw pain set in. Those symptoms seemed to have resolved except for the full- body muscle twitches, and minimal jaw pain. Just to state, I felt 110% the instant before all the symptoms started to happen.
