Liver Herbs Make me Tired......?

I have done 2 very successful liver flushes, I am too nervous to do another. So I am using herbs, Milk thistle, dandelion, tumeric. And I was using a nutrient supplement called Ultra Clear Plus.
I woke up this morning with good energy but irritable so I took just a tiny bit of the Milk thistle, dandelion, tumeric and got calmer but very tired. This happens anytime I do something for my liver.

Does anyone have any experience with this? How long did it last? Anything besides lots of water to help it?? Am I on the right track or just making myself miserable?

Thanks.
