LF and sinus problems

Hi fellow liver flushers,
I,ve been planning to do my fifth Liver-Flush since a week and a half ago but because of flu and a nasty sinus infection I had to postpone it.I'm at the tail end of the sinus problem,just stuffed up so I,m wondering if I can go ahead with it tomorrow and get rid of these toxins! Any advice would be very welcomed.
Thanks and happy flushing to all!
Surley.
