Sorry to hear, that you are going through the same hell.
My insomnia,throat and even sinus problem are mostly behind me.But energy,digestion,memory and a bit of anxiety is till there.
Its easier for me now,coz I was diagnosed and I know sometimes its Die off and that there are people here who got better.Just dont listen to Anthony,he is weird.
My first advise is to do comprehensive stool test.If you got Dysbiosis,Candida or weak immune system it will show.I got combo of all 3 but its pretty normal for candida sufferers I think.
Good luck with diagnosing and sorting your problem.
