Do they still have you drink the gallon jug? That is awful, it hit me about halfway through. Had to finish drinking sitting on the can, I still despise lemon lime flovoring....Luckily I now use cologuard much easier to deal with. My Mom died of colon cancer at 28 from poisoned water at Camp Lejune so I have been getting checked every year since I was like 20.
To your point YES get screened, it might just save your life.
