I was up at 160mg , and my pulse was sky high. They had to take me off of it completely due to an abnormal EKG.

However, now I am back on it. I am only on 60mg so I am hoping I don't have the cardiac side effects once more.

I would proceed with caution with this drug, especially at such a high dosage. I cannot believe your doctor would subject you to so much of this medication.

Alas, I'm not the one with the degree, but still...it is dangerous.
