Just wanted to thank all of you who replied to my post. It really helps to put these thing into perspective when you hear that you are not alone and that the cause is technical i.e. either the illness or the meds rather than personal.
You will be glad to know that by using a combination of your ideas and suggested techniques things have improved and there has been no incidences for a few days now so I am keeping my fingers crossed. Also The District nurse is going to raise it with the Doctor in case there is something that can be / needs to be done with the meds.
Thank you again for your input. This web site is a bit of a life saver at times. It helps so much just to know you are not alone. So glad I found it.
I wish you all the best New Year you can hope for in these trying times.
