Toprol-XL and old lady

I am a very healthy 71 year old lady with high blood pressure. I am taking lotensen and 100 mg. of toprol. I have all the terrible side affects. Tired, sluggish, no energy, head fullness, weight gain, but I sleep better. It hasn't helped to lower my blood pressure at all. It has helped the anxiety but the side affects drive me crazy. I will see a cardiologist in three days and hope that he will prescribe something that will lower my blood pressure. Good luck to all of you who take toprol. I understand that it relaxes the arteries and veins. It is a dangerous medication and it is dangerous to discontinue without the doctor's approval.
