ok to liver flush again?

It will be 2 weeks since i did my first liver flush. Everything has been going ok except for last weekend when i have had fever/chills,weakness, vomiting(once), achy feeling all over and a migraine like headache.

Thank goodness the migraine is gone but i have a lingering dull headache. I may have become dehydrated from the flush from using too much Epsom Salt but i have rehydrated myself- constantly having water. I still have lower mid back pain which keeps me from walking fast and hurts if i cough. Leg pain + neck discomfort.still feel a little warm at times.
Could this still be dehydration? Is it a good idea to flush again this weekend? I just don't want to make matters worse.
