I would definitely stay away from the medications the dr's are giving you. Are you still on stuff from the dr's?
I wouldn't be taking any medicines except for a good multi vitamin and mineral and other health giving foods and supplements. Many of us are completely undernourished and it is likely the medications the dr's have given you have made you worse in the sense that you are potentially unable to detox properly. For example, do you have daily bowel movements? Are you drinking lots of water? How is your mind? Are you able to think straight or do you experience brain fog?
All of these things are really important to protect yourself from all kinds of parasites. Have you thought of a parasite cleanse?
