Members shared mixed experiences with B12 supplements for fatigue, brain fog, and dizziness, with some finding tablets ineffective while others felt that shots or specialty vitamin formulations provided noticeable energy boosts and improved daily function. Several members described practical strategies, including requesting B12 injections from their doctors (though some faced resistance), purchasing over-the-counter tablets at stores like Walmart, exploring deals through Groupon, or trying stimulant medications like Modafinil when B12 alone wasn't enough. A recurring theme was frustration with persistent exhaustion and the willingness to try anything that might restore quality of life, even when doctors dismissed the benefits as psychosomatic or lacked evidence of deficiency.
