influenza
"I tested positive for influenza B and began Tamiflu the next day. It made me queasy and gave me diarrhea two to three times per day. I took one probiotic a day and ate one yogurt a day and still wound up with the worst yeast infection ever. I used MonistatOne but had to use it again three days later. Horrible side effects for me. The Tamiflu did not help my symptoms until I was on it for 4 complete days."
