Hi Natalie,
Thank you for that information. I've had migraines for 18 years now, not the severe headaches I get ocular migraines (which terrify me), however its the after effects where sounds, lights etc hurt that makes me nuts and my head gets very sore. I do get 3 to 4 headaches a day in general, but a lot of Tylenol will fix that. My doctor is currently treating me for allergies for severe vertigo that I've been getting and nothings wrong with my ears so where do you go from here, however, she suggested I start to take vitamins on a daily basis, which I started on about 3 weeks ago and I can honestly say I have had one minor headache in that time :-) I never made the connection until I read your post

After checking the bottle I take (Womens One A Day), theres 100% vitamin B12 in them, so that is really interesting. Im sure the injection provided you with a massive dose, but did he say how much B12 to take on a daily basis?
