during the study they'll also do ekg's to ensure your heart is ok, and also check for a certain type of white blood cell. Evidently the med can cause this type of white blood cell to decrease too much, so they have to make sure it's at the right level to begin with.
I had my 2 1/2 hour initial visit yesterday, and assuming that my bloodwork comes back ok, will be starting the med in a week or 2. Also, you cannot take more than 5g of Creatine daily, or more than a certain amount of Vitamin E (I think it was more than 1000 mg, but not sure).
LOTS of questions about ALL your health issues, no matter how small, so try to remember when they started! Good luck to everyone!
