I feel your pain Jake, literally...

Even on OWL, where I'm up to 30g net carbs per day, I'm still only getting about 15g fiber per day, for exactly the reasons you mention -- it seems impossible to make it work and keep my calories reasonable.

I've been taking psyllium husk caplets every day, but they just don't work. My daily constitution has become a bi-weekly event, and I don't think that's very healthy. It is something that worries me.
