It could very well have been the flu. I just had it. It hit me like a ton of bricks in one day. Sore throat, body aches, head pain, the works. But the great part is that I only spent a day in bed. Still felt run down the second day but was able to function around the house and go to the grocery store. By the third day I felt pretty much back to normal except for a stuffy nose. I'm totally fine now, still coughing up some leftovers every once in a while so I know it was the flu and not detox.
I was over the flu in 2 days that most people are stuck with for at least a week.
I drank lemon water twice a day, took my cats claw and Colloidal Silver which definitely helped alot.
But my immune system is finally kicking butt and I am so pleased with that! And if you were only sick for a couple of days that means yours is too!
