Day 28; detox or contagion???

Ok, I need help. After three days of phlegm hell (days 1-3 are now officially my second worst detox experience...this was my worst), I am finally getting better. Coughing up big gross gobs of yellow phlegm, not sneezing as much (used two boxes of kleenex in two days), I can breathe again...I'm feeling much better. But people are insisting that I have some cold/bronchial thing and now, even my roommate is saying so because she's displaying the same symptoms as I did when I first started coughing!

How can I explain that this is detox? Or are we actually still susceptible to little contagious microbes? Is this junk in my system caused by a bug? Or can I heartily say that it is junk that has been in my system and was now ready to come out thanks to the fast? People are now arguing that my long fast is weakening my system and making me sick!

Help!
