artluvr09, I can completely relate to you! I was trying to explain to my coworkers how the brain fog felt. I said that I wasn't getting enough brain to my oxygen. ; ) So, that's the new joke. Anyways, there is no pattern to my bad days at all. The past few days have been tough, but I am trying to keep positive. Oh, and the blurred vision happens to me too! It's like my eyes cannot completely focus on what is on my screen. It's crazy and frustrating. I am going to a cardiologist at Emory in Atlanta Tuesday, so maybe he can help me out! If I get any good tips or information I will definitely post them!
