Please help with my blastocystis hominis!

I have suffered horrible symptoms for 4 years and have finally been diagnosed with having blasto after pathology stool tests. After taking flagyl I'm not getting any better. I found the centre for digestive diseases in Sydney but I am based in Melbourne. Can anyone help me with what to do and where to go from here? Sick to death of feeling like absolute shit all the time! Finding a doc who actually thinks this is the problem is horrible, they all keep telling me I have IBS. Tweet
