The cheapest way is doing liverflushes and add a coloncleanse.This is based on Ask Andreas Moritz views. The combination gets rid off parasites too. Buy Seasalt and take some every day on your food so you don't need probiotics. That's what I do.
On the day of the flush you skip the bowelcleanse for a day and then continue. The flush you do every 2-3 weeks till no stones/sludge come out for 3x and then you can go on maintenance a couple of times a year.
