I'm a first time poster! I've had the B12 ampoules in the fridge for 3 months now. I look at them often, but I'm just terrified of injecting myself....I know, what a coward... But today I felt faint, my head was banging and I had to sit down twice on my short walk from the shops. It's a month until my next B12 fix at the surgery, so now, know I've got to get on with this. Could anyone advise me on what needles to get and where? And the least scary way to self-inject? Thanks!
