Thanks. I guess I'll stay on the Chanca Piedra and keep flushing. I am going to wait two weeks b4 the next one. I flushed 3 weeks in a row and I need a little re-coup time. The distributor for Chanca says I can go 60 drops 3x/day for two or three months without a break and for long term prevention 30 drops every other day or so....
