Okay, so obviously, vanilla extract has been determined to be safe in dosages normally found in food, with no real evidence of the effects for larger doses.
During my last pregnancy, I was having lots of heartburn and wanted a "natural" remedy. I found someone who suggested warm milk with a tsp vanilla and a tsp sugar. It was delicious and very effective and I had it at least four times a week by the end with no effect.
This time, I've already had it a few times, but my husband has stopped measuring the vanilla. Two times ago, he admitted he had accidentally put too much in. This last time, he was much more in control (but my opinion is that it was probably still way too much). Anyway, after drinking the milk, the limbs went slightly numb. Not like I couldn't feel them at all, but rather like the muscles all felt numb. The first time was just my legs, but the second time was my legs and arms. I'm a little concerned about the effects my LO may have experienced, especially since I can't find any info on this online. I know it has nothing to do with the alcohol, because alcohol doesn't make my muscles numb like that.
Needless to say, I won't be doing any more vanilla milk, but I just wanted to share in case anyone had any ideas
