I have been on Lisiniprol for a month or so. 10 mg. per day in the morning

I just checked my bp in the evening a few minutes ago because I was feeling crummy. left arm was 166/97 with a pulse of 95 and the right arm was 164/102 with a pulse of 99.

I wonder if I need to be on more. I am 5 ft 8 inches and weigh 180 lbs. I know I need to lose weight and am going to make this a priority! But for tonight...Do I call my doctor and tell her this? I wonder if she will suggest I take it twice a day...
