Is there a connection between Aspartame and HBP or Arrhythmia? I had been drinking 4 12oz. diet drinks for the past year. I quit cold turkey about 2 months ago, and I noticed that my Blood Pressure has dropped from 145/90 to 125/80. My hands were always cold when I drank the diet sodas now they are not. I am a 40 year old male 5'9" and weigh 160 lbs. I'm also in pretty good shape, but I still have the PVC's which began about 1.5 years ago. I also get tired when I'm having the PVCs and my head feels a little bit "out of it". Is that normal?
