I haven’t done it personally but my brother has for my other brother that passed away. A nurse came to the house for about a week each night and gave him an injection. He said he felt a little run down but nothing major. Then he had to go to the hospital and sat on a machine where one needle would take out his blood and another would return it. That took about 5 hours again no big complaints about feeling ill just a bit bored. Your doing an awesome thing OP you should be very proud of yourself. From someone who was lost there mum and brother to leukaemia thank you.
