I can tell you matter of fact that you don't have bad var, but that this happens to some people. I'm on a phone so I'll be brief. My buddy had this happen to him. I tried it and the same thing happened to me. It wasn't blood sugar or bg bc I checked. Literally took one serving and thought I was going to fall over. What's weird is he boiling point tested and it was real and then let a friend try it and he used 100 mg ed into a contest for 3 months no problems. I think this may have to do with potassium bc var strips potassium. My potassium is always low in bloodwork and so was my buddies who had the problem and it's a common genetic thing. That could be your problem. Supplement with potassium and drink powerade zero throughout the day. If that doesn't work, Try a havoc / hdrol stack for similar results to high dose var. those never made me dizzy.
