Now that I'm in the clinical trial, I'm not allowed to add any new meds, even over the counter, until it's through. They know that I could use a blood transfusion, but they want to analyse my blood for this study and do not want to hinder the results in any way. My hemoglobin is 9.1 and blood is being drawn every week. So far they've taken 23 vials of blood in 3 weeks. I'm drained. I have to say that I'm beginning to feel better as far as the pain goes. The frequency is still the same (7-10 x/day - with no control, all accidents). I have to decide if the next colonoscopy is worth going through for a 1 in 3 chance of getting a placebo.
