Oh honey! I know what you're going through! I tell you, there's hope...I understand that our colons have a reaction to the anesthesia and this surgery messes with our digestive tracts, the entire thing...it just takes time for it to get back into rhythm.
Now, that said... If your Doctor says it's OK, walk, gets things going...drink your water, sometimes drink hot water...take your fiber, fiber tabs are fine and you can add Wheat bran to your regular soft diet...I used a mild laxative though I worry about becoming dependent on that...irrigation was always a last resort but was alway affective for low blockages, you can get single doses over the counter.
Remember too that you're getting used to having a WHOLE lot less food in your system...I went from going 2-4 times a day to every 1-2 days.
I SOOOOO get what you're going through!
