I’ve had a few colonoscopies over the past 5 years—the first found cancer, which seems to have been successfully treated, as the followups have found only non-cancerous polyps. The first couple used Suprep, which I found doable but vile. The last couple used Sutab, the pills mentioned above, which I found much easier to take.
There are a lot of other colonoscopy discussions we’ve had. I think the most recent is Ugh, do I REALLY have to schedule ANOTHER colonoscopy?.
