I Had 1 1/2 Glasses Of Wine Ending At About

I had 1 1/2 glasses of wine ending at about 8:15. I am only to take Metoprolol when needed. My BP is 161/83. Hight blood pressure is new to me and I will see a cardiologist for the first time Thursday. My primary care Dr. gave me the Rx just in case for before Thursday. I 1 for 3 times last week but have gone without until tonight. I almost never drink but I did tonight. I am trying to decide whether to take 1 pill tonight or not for 2 reasons:
the mild alcohol intake as well as trying to stay off of it before I get to the cardiologist so any tests will not be skewed. Ann
