Diverticulitis
"Have used once or twice a year for last 10 years and start to have relief within 24 hours with symptoms usually gone by day three.  I take two a day after first tinge of pain (you know what I am talking about) and continue for one week minimum or two days more than symptoms persist.  Makes me a little fatigued and I start to get diarrhea after about 4 days but it is worth it."
