What symptoms made you think you had parasites? I am very thin and always have been no matter how much I eat, I was always sick as a kid, was on penacillin so much I became allergic to it. In the passed few years I have only gotten really really sick like fever and flu type stuff once or twice a year. What do you think? Also, when will I stop feeling lathargic from the Clarkia ? I am on day 2 and am taking 5 drops in the morning and 5 at night, its the double extra strong Clarkia , is this enough? I feel like crap from it so I don't want to increase yet. What do you think? I'm so confused there are so many ways to take it!
