Well, I cannot say that I have experienced this, but shed some light on the subject.
Your body, most likely is very toxic, especially after taking so many toxic meds.
First, I would do a kidney cleanse, then Colon Cleanse then I would do Liver Flush and detox the liver. So it can clean your blood and thus all the organs. Then after three flushes go on a water only fast. Brush your skin everyday twice or three times.
I don't know your diet, but diet is where our major problems come from. If you are not already on it, go on a plant based diet. Stop all processed foods and heavy meats.
