It's not what you take but what you don't take!
You dont say whether the drugs are of the prescription variety ot not but the technique of detoxification process is basically the same,
Start with an enema and a three day juices-only diet. No solids whatsover.
For the following four days add hot cereals, boiled vegetables, cooked fruit and soft boiled eggs. At least one tablespoonful of Olive Oil daily andf a weekly enema. Follow this diet for two weeks. Thereafter gradually add poultry and fish.
It goes without saying that tea, coffee and smoking are stricly forbidden.
Take a regular dose of Thuja 6 (Homeopathic) each day.
Good luck!
