Metagenics UltraMeal

Does anyone else get massive chest pains and headaches when they take UltraMeal by Metagenics?  I have heard so many good things about it but I feel like I am going to die 3-4 hours after drinking the shake.  Now typically most people would just stop taking it - but I have not found one bad claim about the product which leaves me to believe that something more serious is going on.  Is there a chemical reaction going on in my body?  Are the nutrients trying to fix the areas of my body that are possibly compromised and that is why I have the chest pains and headaches?  Or is this food some kind of detox that is making me sick?
I confronted the Chiropractor whose office I bought it from today and she said that the UltraMeal has detox like ingredients and my body could be responding to that, but after reading as much about it as I could on their website - it does not say anything about using UltraMeal as Detox.
Does anybody know anything I don't know about this Metagenics UltraMeal and/or what in that meal supplement would cause really bad chest pains and headaches?
