Just a little advice. I felt like my heart was beating too fast so I had my pulse checked andit was 107. Which is too high. My mom has potassium trouble so I figured that I must be going through the same thing well I just ate more tomatoes. Try to eat things that are high in potassium and low in carbs. I wouldn't advise anyone to take potassium without consulting with your doctor first. The doctor told my mom that have low potassium could cause a heart attack. That's what happened to my grandfather. My mom is on atkins and she is trying to follow it the best way possible but when she starts getting cramps and her heart starts beating fast she has to do something. She is taking potassium perscribed by the doctor.
