Sinusitis
"re: side effects, I forgot to add to the comments I just submitted that while my stomach felt a little weird the morning after my first dose (this being 12 hours later) I was prepared to eat plenty of probiotics, which I have been doing. I have not had any problems; I am really pushing the yogurt and kefir. I did feel extraordinarily tired but not debilitated, and I was extremely fatigued from nearly 5 weeks of being sick, so the trade-off is meaningless, and it&#039;s improved after the first mega-dose anyway."
