How much hc were you taking?
I took 2.5 mg to start with and was supposed to work myself up to 25 mg. I got severely ill at that point.
HC destroyed my adrenals and caused the worst crash I have had. I am still in it--since 2009.
I've written about it many times, so that's all I want to say about it at this point.
It's very painful to remember how much better I was before I took HC.
