I empathise with your problems. I have the same symptoms - all except nausea. I went from 190 to 140 pounds. Then I was put on tetracycline for 4 1/2 months and the weight loss subsided. I regained back to 180 which I am now. But my symptoms are still here. I am currently on the Master Cleanse. After 5 days I feel no better. 5 more days to go.
If anyone has any advice, please respond.
