We're living a very similar lifestyle Copen. Sounds like it's treating you well, seeing as you're able to be as active as you are. That's awesome! I've avoided the water fasts as I don't have much weight to lose either. I put myself into ketosis for a short while and was very low carb before and after for a while. My Wife said it was the worst stint of our marriage. Adding carbs helped and I noticed even more help after I started taking this stuff;http://www.allstarhealth.com/f/gaia_herbs-system_support_adrenal_health.htm
If I don't have time to visit the farm where I grab my grass-fed meats, I always fall back on frozen New Zealand grass-fed lamb from the supermarket. I use a bit of home made ghee from time to time but not often.
No rush on the PS. I'm taking a two or three day break. Gas subsided completely almost right away.
I found this article about the potential benefits of switching sources of RS and adding various probiotics etc. We're up to date on most of the other info but at the very bottom "Supper Booster recipe - Mix it up:" there is some really good info, in my opinion.

Dr. GBG and Tim Steele have agreed to go over my MDX 2200 when it's complete. I fully meant it when I told them they are super heroes.

Side note. I used to always(10 years) have cold and often clammy hands and feet. Since I began taking RS, it's completely better 90% of the time!
