HI Dolly, awful having the 'lergy' is'nt it, hope you soon feel better, but as you say the cough is the worse thing and the last to get rid of. I haven't been sick at all in the last few years so can't help you there I'm afraid.
Doc wanted me to speak to some students about explaining what it's like living with a long term illness, but I didn't think I had enough insight into parkinsons to help them in any way. I've had the dreaded disease coming up for six years now and still don't know enough about it, but not to take me off the list as I may be of help in the future. It's a good thing as it helps 'spread' the plight of PWP, so good for you. I think I would end up crying and showing myself up the way I am at the moment, I don't like confrontations. I've started to see a therapist now, had my first session last week (in tears!) can't get to the base of it all, as you say could be my meds, which the parkinsons nurse is looking into for me.
Take Care hope Mr Dolly is keeping well - Sheffy x
