You should do them every other day during the first weeks. I have done them every day for 3 continue weeks.
It is very cheap to do them. You only need distilled water, salt, sodium bicarbonate, or nystatin powder.
Any kit works. I do them using fleet bottles. You have to do 3 or 4 rounds using 2 bottles each time until the water comes clear. At the end, when you have emptied the colon is when you see fungal colonies coming out.
What do the fungal colonies look like?
