I would like to thank a person who posted a "treatment" for constipation in PD (from their experience).
Im sorry i cant find the post (think it was a reply to someone) so forgive me for not using your name.
I now drink 3 glasses of water when i wake up in the morning then wait 45 mins before i eat breakfast. This has made a huge difference to my digestive system in a positive way.
A bonus is that it is free, medication free and healthy.
