Dont Drown Your Sorrows (or Joys) in Alcohol While celebrating your B12 shot or unwinding after a long week might involve a drink, its best to avoid alcohol for at least 48 hours after your injection
It represents a precautionary approach given limited long-term data rather than a response to documented concerns

Energy may improve briefly, and that can lead to behavior changes that sometimes subtly change weight, but the vitamin itself is not a fat-burning drug
