I plan to buy some B-12 and give it a try. Most of the time I do not have anxiety to any great extent, but when I do, it really does a number on me. Was recently taken to ER because BP was over 200 and head felt as if it would explode, plus being nauseated. I feel as if I cannot function at all. They kept me overnight and actually did a CT scan. Feel so foolish when it is over. I do take something for mild anxiety. My mom used to actually have her tongue swell and could barely speak when she had a panic attack. I hate it.
