Thank you. I got the b12 in the 1000mcg and I was mistaken the b complex I think has 15mcg. The multi I take has 6mcg.So assuming I still have high b12 and the doc said to lay off for a week and it may be a fluke but since I stopped the b complex I feel worse and more symptoms what should I take? Should I take just the b complex or just the b12 or both?
