Unbelievable!
Actually, I'm speechless, but felt compelled to jump on this and say SOMEthing!
I certainly don't claim to know much, but I DO know that doctors take an 'oath' of some sort....
If your doctor is truly aware of the state you are in, there should be SOME way he can communicate with your ER so that they are aware of your condition. The ER needs to have on record your specific diagnostic info, so that when you do show up in a state of emergency, they'll know what they are dealing with. You should ask your Dr the very question your thread asks and he can advise you on a care plan ahead of time.

As far as the Magnesium issue, MrsD would be a good source . She is VERY knowledged in supplement info. She's on the PN forum alot, or she would welcome a private message. Your issue sounds pretty much like a crisis to me, so I'd go straight to the source!

I'm so sorry you are dealing with this
