Is there anyone that experiences very severe and strange side effects from b vitamins? I tried b complexes and they just made my head foggy, dizzy, sensitive to light and didnt feel good so I bought individual B's. I have tried b12 extensively for methylation and b-12 protocol and it completely jacked me up. I had trouble breathing where i went to the ER, my pulse ox was around 88 upon exertion and continued to drop. All sorts of weird stuff. Brain fog, depression, feeling extremely toxic and ill. I tried b6 today to see how I do on it and took 10mg of P5P (active form of b6) and immediately felt sedated and a little spacey in the head. (Spacey is never a sign of good for me following supplements). After about 15 minutes, I was so sedated i went to the room and completely knocked out for a good 2 hours cold. I know b6 is a sedating and relaxing vitamin and welcomed the sleep but the biggest side effect was I had trouble breathing. It felt like my lungs or airways were so suppressed and i couldn't breath. I have read that 4 cases of respiratory arrest have occurred (1 each year for the past 4 years) from b6 but i cant imagine 10mg doing that to anyone. I woke up and couldn't breath. I'm drinking tons of water to flush it out of my system if that's even possible to speed it up. So b12, b6 is no go for me. I have on that list b2, b1, b3, and pantethine and folate. For some reason, b5 is okay for me even at the 1000% dose, I actually don't even notice it. Perhaps I have some sort of methylation or pathway block that supplementation with b12 and b6 is making worse. Anyone have these strange reactions?
