I wouldn't recommend this under usual circumstances but with sfn I think you need to be prepared. Tramadol - I take it only when really desperate. It kicks in for me in half hour and you have 24 hours joyous relief. I then won't take it again for another week, two weeks maybe. You will already know about the addictive risks associated with this. The good thing is you can take it as and when. It hasn't caused me any problems at all. I just wish I could have it every day as it also makes me feel good and have some energy and I feel better all round on the days I have it.
