My doctor began giving it to me the week of my heart by-pass surgery. I also take Avapro for blood pressure, Zocor for cholesterol, and metoprolol ER Succinate. I can go about 24 hours without taking the lorazepam. I get sweats, flushed face, burning in arms, and over-all anxiety. I feel I have no reason to be anxious at this point since the surgery went well and everything seems fine. How do I quit taking it?
