My only comment would be it is your body, you run the risks, you get the benefits so it should be your choice.
If you are asking for information to get a doctor to prescribe LDN:-
The I would suggest the main evidence base is Anecdotal

In the end however it is down to negotiation you can not demand any doctor prescribe LDN
There are plenty of doctors that will prescribe LDN privately.
I have over the years helped a fair number of people prepare a case to get their own NHS doctor prescribe LDN and to date only had one failure and even that doctor agreed to monitor the patient and helped resolve problems they had.
Getting it prescribed on the NHS is much more to do with you PCT policies that the doctor, although of course you do need to start with a NHS doctor prepared to prescribe it before you have any chance of getting a NHS prescription.
I have never however had any experience with anyone who wanted to mix LDN with Tysabri so have no idea if that will add any difficulty in getting a prescription. I am sure however if it is what you want to do you will find someone to prescribe it for you.
I agree with you however the chance of anyone funding licensing trials is extremely low.
