There seems to be very few on the bovine, when I went to hospital a few years ago with a bad chest infection, the hospital had no stocks at all, and my son had to go home and get some from the fridge. The chemist has had problems occasionally getting stocks. I feel very happy on it though, how about you? I still do the daily jabs, my chemist says with modern technology, I am still at the Betamax level. Have now got the pen to learn to use, but not started yet. At 64 I wonder if the pump is an option, but I am so use to doing the injections, it would be like loseing an old friend. Thanks for replying, keep in touch.
