I started b12 shots four weeks ago, 25ml a week, and am feeling worse since starting. The first few days after I am super extra fatigued but unable to sleep, dizzy, anxious, nauseous, and have a headache. The symptoms get somewhat better after a few days, but do not go all the way away, but after my next shot they ramp up again. Has anyone else gone through this? My b12 was insanely low before starting and was told I have the MTFHR mutation and also popped positive for intrinsic blocking factor. I’ve been vegetarian since I was a young child and am almost 30 so it’s been a long life without adequate b12.
