I personally have liver/gallbladder woes. That might be the cause of your upset stomach.
Have you talked to Dr Bailey? She told me to do a liver flush. The first one I did, didn't seem to produce many if any stones. The second one I did (just last week) Produced many, many stones. Green ones. I was happy to see them go.
I was kind of sick the day after but now I am feeling much better..... I am still not healed. Although my tongue is better since the parasite cleanse, it still acts up off and on.
The Liver/Gallbladder flush is not a fix... it just gives you some relief.
I just started today on the Liver/Gallbladder cleanse. It is going to take awhile to heal my liver but I WILL HEAL IT!!.
As for your sore throat.... my sister who also has liver problems has a sore throat when her liver/gallbladder acts up. I get a burning tongue.
Neither my sister or I were drinkers so that is not what caused our problems.... I think it was the parasites that caused my problem.
I will be doing a review on my blog about the parasite cleanse.
