Like avenirup said, you overdid with the stims. You should wait at least 4 hours inbetween ECA doses. Next time take just the home-made ECA stack about 30-45 minutes before the gym.
overstimulation of adrenals and desentization of some peripheral systems gave you a feeling of oversatiation, plus the stimulation and exhaustion from cardio - hence desire to puke.
and there's no (or there should NOT be) general guideline as to when and how to take your ECA - it depends on your tolerance, some people start tripping off of a cup of coffee, while others go as high as 150mg+ of ephedrine a day along with other stims and still complain of lethargy
