I don't know what it is, but since I've been back to work fullish time (still only doing about 7 hours, 7.5) I go poop every day while I am at work.  I don't eat anything different, protein first, veggies, carbs (in that order) and drink my 64+ oz of water everyday.  It is still kind of painful to poop - been that way since a few weeks post op when constipation set in for me.

I have a couple theories.  I am more active now that I am working, constantly getting up and walking up and down halls, as opposed to sitting in my chair most of the day.  I also drink more water when I am work - 2 32 oz nalgene bottle's worth, PLUS my protein shake made with milk PLUS usually about 16 oz's before work plus whatever drink at night.  So I am sure that is helping a lot too.

But I really noticed this week, now that I am back to work, I am going pretty much everyday now instead of every 3 days.  Now only if I could remember to drink as much on the weekends and remember my calcium at meals, I will be golden!
