I have fully formed bm's, which was achieved through diet. However, please bear in mind that everyone is different and what works for me may not work for your daughter. I follow the following rules:
1. No Processed sugar (candies, cakes, sodas, fruit punch, gravey made with sugar,
cookies, cereals, etc.)
2. No Dairy (especially milk & cheese, no breads...eggs are ok)
3. Reduced carbohydrate intake (less rice and spaghetti, etc.)
With these guidelines my bm's became fully formed, but it requires tremendous discipline to follow it. My energy levels also increased while following this...it's not a solution by any means, but it made my life more bearable. I saw results within two weeks of following this, BUT breaking the rules will cause swift setbacks/relapses.
My guess is that following this guide in 'addition' to her meds, she will see results quicker than expected. Do not stop taking meds unless her doctor/GI says so.
