As I don't have the condition, I apologise if you feel that I'm wasting your time. However these links might help:
Firstly, the NHS website offers plenty of information about the condition:
http://www.nhs.uk/conditions/Trigeminal-neuralgia/Pages/Introduction.aspx
(The 'Treatment' link might be of particular interest to you)
Secondly, the website of the charity helping sufferers might be useful:
http://www.tna.org.uk/
In particular, I note that there are a series of four 'personal stories' available to members via the panel at the bottom left of the page. (It's £20 per year for membership but, if TN is causing you serious problems, you might feel that it's worth it).
The information here, from another UK charity, might also be relevant:
http://www.brainandspine.org.uk/trigeminal-neuralgia
Again, please accept my apologies if none of this helps.
