You can't 'kill' candida... your immune system has to get to a stage where it can turn the fungal infection back into its benign form. So, you build up the immune system.
In case you needed more convincing, look at all of Bee's success stories...
and sinus pressure is classic candida as it ferments sugars and your body produces mucous to rid your body of the offending food. Also dehydration as your vascular beds all tighten to conserve water (and if you're lacking in sodium, water will have to be conserved even further),
