my 4 year old grand-daughter has it for chronic constipation. Two poos in 6weeks so bunged up big time!! The only difficulty is in getting it in to her. it tastes horrible even with added orange juice.However they are persevering and she is gradually un-bunging. Poor little girl, it must be so uncomfortable for her!Don't know why I'm telling you all this, but yes Movicol works!
Whatever happened to good old-fashioned senna pods? No fuss, no namby-pamby waiting 8 - 10 hours lark, boil 'em up, drink it down and bang! business done!
