Not the case: Your symptoms are not from B12 toxicity. 1st, B12 toxicity is rare. 2nd, if you do happen to become toxic, then your symptoms would be numbness/tingling in the hands ; face, panic attacks, insomnia, and maybe rashes. If you already have an overactive thyroid or mitral valve disease, then B12 toxicity may make those worse. Dyspnea would result from worsening mitral disease but you'd lose weight.
