So, I went for my flunpenthixol injection today and it went very well. Total calm soon after. The 50 mg dose is important. It may give me a brain tumour or not, but it helps me IMMENSELY. I don't know how much I was injected. I did not check. It looked like a lot but my GP is excellent with mental health stuff. It is good to trust health care professionals who deserve your trust like he totally does.
