Hi everyone, thank you once again for your replies. I am *really* appreciative of them!
First of all I am really warming to the idea of this tummy fiber because ideally some kind of predicable pattern would be nice rather than four days of pain and c then a mass urgent evauation as my innards wake up and realise the backlog!
I am desperate to include fruits and veggies in my diet so I shall persevere and try that form of fiber first then think about a supplement. Anything I should try first / avoid altogether?
