Over the past 4-6 weeks, I have had huge, hard bowel movements. Stool softener help, but not a lot. When I use a laxative, It become very loose. My last colonoscopy was two years ago. Previous colonoscopies there were always removal of polyps. A am a 62 y/o woman who drinks a lot of good old water all day long. I have not added or deleted any medications for 5+ years. I inject 80 U of lanus and 100+ U of humalog per day, plus 2000mg of Metformin per day.
