Yes, you can take the Fibre89, fibresure or PH with your shakes each day throughout the diet to prevent constipation. They wont effect the diet
Senna can only be used occassionally (if you have constipation)
Never use the Fibre89 etc if constipated as it will make it worse. Just use them to prevent it happening in the first place.
The fibre89 and fibresure don't taste of anything. You can either put it in your water, or add a teaspoon to a couple of your shakes each day
Makes the whole diet so much easier without the dreaded marbles IYKWIM
