The diet is a little outdated. Do not use artificial sweeteners. http://www.rsdrx.com/four_f's_diet.htm

You might want to look at a Paleo diet as well. http://www.marksdailyapple.com/#axzz3PrYKxdtn

Not every medication will react the same way, you essentially have to try a few weeks to a month to test them out. Low dose naltrexone seems promising without any major side effects. http://painsandiego.com/tag/low-dose-naltrexone/

Even if you ultimately decide to use opiates some day, realistically you won't be pain free, but you won't have to deal with the highest levels of pain.

My short list of things to try: Lidocaine patches, warm baths with Epsom salts, Epsom salt cream, swimming/pt in warm water, deep breathing/learning to meditate, and consider a consult with a pain psychologist.

There is no reason not to try Ketamine. You might want to check out one of the active CRPS Ketamine groups on Facebook.

I break up my activity throughout the day. If I can only manage 5 or 10 minutes of an activity, then I wait until my pain returns to baseline before restarting. This is MUCH harder with a young child of course. If you can afford it, I can not stress how much easier your life will be to get cleaning help in once or twice a month and buy a zoomba if you have carpet.
