Hello Emrys and welcome! If you have only been diagnosed two months ago and are just about to become a father, I'm not surprised that you are worried.
To start with, I would suggest you send a private message to CureOrBust, a man with RRMS who actually lives in Sydney. You might already know him, of course because his GP is open to the treatment. I wish a few more were, because, as you say, what have you got to lose? The abx which David prescribes are harmless enough and are used for long term treatment of something like acne, for goodness sake, unlike another antibiotic gaining vogue: INH which needs constant liver monitoring and which David has said, he would be banned from practising if he prescribed it to patient who the became seriously ill.
Many people in the early stages of the disease sail through the treatment with no difficulties. In fact, without even realising how much better they are getting until it is pointed out to them that a few months ago they had difficulty walking 50yds without stopping, but now they can walk to the hospital with no trouble. Basically, the longer you wait the more difficult it is likely to be, yet if you don't have a long history of relapses or, like me latterly, just plain progression, you will find it difficult to know if it is working. Your deficits will go away, yet you won't know if they will have done anyway. When I was in my twenties my relapses were so minor and my remissions so complete that I wasn't worried. I thought it would always be like this, then suddenly it wasn't.
I won't tell you that you must do it, you have to make up your own mind, but if you have a GP willing to treat, you are halfway there. He is always welcome to contact David, whose address is at the bottom of this page:
. You are also welcome to write to him.
There is also a fairly new site, http://www.CPn Help.org
, which has lots of information about abx as a treatment for MS amongst other things. I post there as Sarah rather than Anecdote.
Take your time, have a good think about everything, ask any questions about anything you are unsure about.
