Hey Boo, I had the exact same problem. I hadn't gone in probably 10 days or so. Started with the fibercon and took ducolax for 2 days and nothing. Nat suggested glycerin suppositories so being desperate, I tried them and they did the trick. Ever since then I stay very regular on my 2 doses of Fibercon a day, and feel much better. I would suggest to anyone in this WOL to be absolutely sure you're getting enough fiber so that you don't have to go through this too. Take preventative action if you aren't so afflicted yet. It's no fun!

Happy low-carbing everybody and have a great weekend!
