I was prescribed sulmeth for a sinus infection. I had only taken the first dose and about six hours later I was almost on my way to urgent care. This poison gave me a 103 degree fever, the worst migraine you could ever imagine, extreme diarhea and gas that didn't stop until about three days after taking only one pill, my bones ached, and extreme thirst. If you are prescribed this poison for a medicine, i suggest you throw it directly into the trash or prepare for one of the worst days of your life guaranteed. This is no joke.
