The absolute worst experience I had with diverticulitis was when I thought I was over it after about 4 days so I stopped halfway thru the Bactrim (which I hate) and talked myself into believing it was a false attack. A few weeks later it came roaring back and I had an attack that almost killed me despite restarting the Bactrim & clear liquids. I’m guessing you only have one chance to beat it and you better give that chance all you’ve got and not fool around the way I did. Despite how much you hate clear liquids and antibiotics. Don’t stop treatment prematurely.
