Sorry to hear that about the helpline - I am sure someone from PUK will pick up your comment through moderation of this site.
You know more about your meds now and how they affect, you which is the positive to take from this....
I guess your local pharmacist would have been someone to have called..
hope it doesn't happen again.... good on you for working out what to do.....which does seem to be what PwP have to do
Best wishes and enjoy your Christmas
