Soluable or insoluable? More or less?

Hi everyone, I'm still fighting this fissure, and just gave myself another micro tear.

I take two doses of Restoralax each day for over a month (one dose a day for months previous), and still can't get my stool to turn into pudding. This morning it was a regular sized movement. I don't understand.

It could be that over the past two dinners I had Schar gluten free pizzas. Maybe the carbs and too much fibre bulked me too much?

I try to keep my fibre down to about 16 grams a day, mostly through fruits, vegetables, and oatmeal.

I'm so confused about fibre. Some sites say eat a ton of fibre, others say cut them down.
