you may have had an anaphylactic (sp) shock!
introducin somethin new into the system can trigger that.. and its dangerous.
i had it once ..... i couldnt breath properly , i felt extremely sick suddenly i was confused and withdrew into myself.. and i physically looked like i had just completed a marathon!
the doc gave me a high dose of piriton and the symptoms eventually subsided after an hour.
that was some crazy s'hit....
