Well, I too have been through the mill with lb. I had my blood pressure that low too many of times. I never could understand why my pulse was high yet bp low? Now, that I've gained weight I have high bp. I'm taking Garlic to lower it, Hawthorn to regulate my heart, and all my vitamins, minerals. Have you went to the health food store. Believe me when I was tired of meds that is where I went and this stuff really works. After all when you have a heart attack they check your enzymes and minerals. Potassium is important. When my bp was real low I would just rest with a sedative. Rest as much as possible. How long has this been going on?
