In begining of 2nd flush.....and flushing already?

I am in the beginning of my second flush. I took the 2nd dose of ES about 30 min ago and I am already flushing! Is this 'normal'?

Also, I feel rattling in my liver area. I had a gb attack yesterday afternoon. ES and my homepathic stopped it. But I have felt that grumbling ever since. But alot after the second ES.
