I took Sulfa for 6 days and was in bed for an entire day with chills, high fever, and no appetite. I ended up in the hospital with 105.5 fever for 4 days! I am still drinking tons of water to wash the poision out of my system. I also broke out in a rash all over my body twice - on the 7th and 8th days after starting the medicine. I was given Sulfa to fight off a staph infection in my nose.
