Mum has  bladder cancer but today seems to be slipping in to a deep sleep almost like  a coma if  that's the right way of putting it the trouble is  she has to have  her antibiotic medicine but she's not waking properly I'm worried about if she don't  wake up properly for me to give  her medicine should I ring 111 she's 90  I don't want to worry them really but I don't no the best thing to do thank you.
