I Have Panic Attacks,now, I Was Taking Klonopin (generic-CLONAZEPAN) 05.mg

I have panic attacks,now, I was taking klonopin (generic-CLONAZEPAN) 05.mg for 20 years and 1 each night...Suddenly the provider of this did not have the same brand I was taking and the pharmacy sent me other brand: MFG ACCORD in India (INTAS). Call the pharmacy and was inform:"Our regular Supplier did not send).
I took the pill (which I could never stop ONE each night) and the next day I had these terrible unbalance in my body: my head, palpitations, in other words out of my mind, asking God to take me away, instead of having these problems.
