First flush and feel miserable

I did my first Liver Flush last night and I had a headache and very bad nausea all night. I had dry heaves this morning around 6am, hardly could get down the remaining Epsom Salts . But the nausea and headache continues today. Is this a detox reaction?
On the up side I did pass many small tan colored stones and about 30 green stones of different sizes. Tweet
