I had a loading dose of B12 and all was great for 6/7 weeks, I felt normal, had energy etc but after that time the good effects started to wear off, so knowing I was due mid November and the nurse had said that some people felt the need to have the next booster a little earlier, I've waited for a further 4 weeks throughout October gradually feeling worse and worse with less energy and more tired. I phoned the GP and made an appt. Got there and she said she wouldn't give me the jab. Boy was I annoyed. I noticed that when she was looking through her notes on the computer that the price of a B12 jab was listed and it was pence. I'd happily pay to have a B12 jab every 6 weeks or so. I can't manage on one every 12 weeks. I will probably be back to square one by the time I finally get the jab in 2 weeks. Anyway, I needed to offload. I'm feel helpless and livid, livid, livid at being at the mercy of someone else just so that I can feel normal and live a normal life.
