I swallowed my two magnesium capsules with activated B6 in them and about 5 mins later I belched a sweet powdery spray belch up in my mouth that’s never happened before ever! It’s been a day 
I pray those capsules with the magnesium with activated B6 didn’t bust open when I belched the spray powdery sweet in my mouth get in my lung or whatever today’s has my anxiety high .. that has never happened before and I been taking them for over a year or so
If it makes you feel any better, I threw up Tylenol during a migraine. It basically turns into white fluffy stuff in your belly because that’s exactly what I threw up. I had all sorts of white bits of Tylenol in my mouth and had to brush and rinse. I would think magnesium and B6 would be okay because at least those are things our bodies need and are not poison. I understand the anxiety…believe me, I do. xo
