After having problems with the daily elimination process (didn't I phrase that tastefully) my doctor suggested Movicol a little sachet of powder dissolved in half of water works like a charm only BEWARE read the contraindication instructions in the box I didn't and suffered two weeks of unexplained severe PD symtoms
It seems the movicol has the potential to interact with other meds we take by altering their absorbtion so we only get half the effect
I was totally ignorant of the reason why my meds were not working anymore even going off Thiamine thinking that was the culprit So be aware lovely people read the fact sheets of any new meds you take by the way this info does not specifically mention PD but I'm telling you it sure does affect the meds that are our lifeline
Be Positive
