Hello,
I just came across this forum and saw your post.
Unfortunately that is sometimes how it is. My suggestions are drinking a lot of water to flush out the toxins. And calling your homeopath, mine would give me a smaller dose, like a 6c to help me ride out the healing crisis.
That is how healing goes sometimes, but you will get better. I was told it is like pealing the layers off of an onion, you do one layer at a time.
