Update on EKG. No blockage, no plaque. I'm relieved. I take Flax Seed everyday with vitamins. Pays off I guess. Cardiologist said all looks great! Still having headaches though, Only been about 4 weeks since I've been off Toprol-xl. Recently saw a Doctor that occationaly goes on tv for health updates. We talked about Toprol-xl I mentioned he needs to do a show on this product. He said he might. He is aware of side effects it can cause. My physician started me on Cozaar now for my b/p. High b/p makes her uncomfortable. She feels it may now be needed. I'm considering going off it all together. I still feel it would balance out with time.
