Has anyone else tried Azithromycin/Xithromax for CFIDS and had it make them worse instead of better? I'm flaring like crazy on it and it's into the third week of taking it three days a week. I'm not sleeping well on it. The three days I take it, even with acidophilus, it's causing my stomach to be so upset that I can't leave the house. My doctor wants me to stay on it for three more weeks because some people do get better after a full six weeks on it, but it's making me so ill, I don't know if I can keep doing this. Like the treatment is worse than the disease at this point. And it's hard for me to tell if it's doing anything to help me because it's making me so sick.
