I would start with a colon cleanse and liverflushing so these organs are free flowing, so the toxins don't get reabsorbed.

I was for 40 years on amphetamines, 15 years on 3 anti-depressants plus several years 3/4 prescription drugs. After a couple of months I contacted Andreas Moritz and started reading his book. He suggested to stop taking the drugs if I could, including not to use over the counter drugs.
I had liver flushed already for 8 months, improved lifestyle and using oxypowder for colon cleansing.
I did stop and it took me 10 months to get my liver free of stones/sludge 3x in a row.
Since then I have kept reading and made changes according to my bodytype, but I still keep my liver and intestines clean. I get sluggish when my liver needs flushing.
