You may want to wait longer than 2 weeks, if and when you attempt your next LF. I think it was Andreas who said we should do the flush once a month, because the liver needs time to "recuperate".
My 2 cents...
Would be interesting to hear what the experts have to say. I too have only flushed 4 times and the 4th one was up until now the hardest. Good luck and God bless!
