Hi Lady bag, first of all
Tiredness is one of the things with PD. As chook says, have a word with your nurse.It could be you need to tweek things a little. We have just come back from our unit, my husbands iron was really down and he was very fatigued so they are giving him a 3 course of iron infusions. It could quite easily be your BP meds. Please have a word with your nurse, that is what they are there for.
