Whilst the above could be good advice in general life, on CD please do not use anything with sugar, citric acid, etc etc.
If you are prone to constipation and you are on CD please use the Fibre 89 twice a day or the psyllium husks to prevent constipation.
If already constipated use Sennokot and glycerine suppositories to relieve the problem then continue with the Fibre 89 or psyllium husks each day do not wait until you get constipated - prevent it.
