Anyone had Sepsis?

After a couple days of feeling poorly, with extra phlegm, fever, SOB and malaise, I went to urgent care. While there I became faint because my blood pressure dropped to 80/50.
They sent me straight to ER who found elevated lactate (sepsis marker), high WBC and metabolic stress, so I was admitted and treated for three days with sepsis protocol. I can't believe how fast this came on. Now I'm paranoid of a reoccurrence, which statistically happens to about a quarter of patients within 30 days of the initial incident.
Would appreciate comments from anyone who has experienced this.
