I have a feeling this isn’t the full protocol? Having had an appointment with Dr Weir recently there was more to it then this. Just an FYI.
What I posted plus advice to my doctor on B12 & folate this was all Dr Weir gave me. As a very long term ME sufferer with a long history I was surprised if I’m honest.
ETA: I saw him in January this year so very recently unless he’s changed it all since then?
