hey. i know this isnt a psyche med so this may seem trivial to some. Ok this is slightly embarrassing... Anyway im going in to hospitaal 2moro to get screened for bowel cancer and i need to take this laxative today called picolax. i just wondered if anyone knew how long its ment to last? or anyone who has been on it before could tell me how many days before my bowels go back to normal? cheers. chris.
