So that your face doesn't look like the icon on this post, I'd like to recomeend a fiber supp. that has worked well for me.
You can buy it at Vit. Shoppe but I am sure most places have it.
The nice thing is that it comes in powder and capsules...which are very convenient. The powder even tastes slightly sweet while doing lower carbs.....note the word slightly.

Anyway--if you haven't found something that works for you, I thought I'd pass this along.
