I had the first of a course of B12 injections at my health centre two weeks ago. I feel a lot better in my self but have experienced dreadful insomnia ever since. It was like flicking a switch and from the first night I didn't sleep more than an hour at a time and had to get up frequently to pee throughout the night. Two weeks later and these symptoms are continuing - sleep for an hour, get up to pee, repeat up until around 3 am then wide awake.
Has anyone else experienced this and if so does it get any better?????
