Hi,
I have been on Atkins since July...recently added MSM to the mix.
I noticed right away that low carb cleared up most of the brain fog. When I added MSM, the feeling like a Mac truck had hit me every morning went away.
Now, don't get me wrong, I still flare, but now its only the pain of the flare, not brain fog and constant fatigue as well.
I am down around 30 lbs and feel way better than I have for many a year... I wouldn't say low carbing has cured me, but it has made life more tolerable. Instead of feeling ucky most of the time, now its just part of the time (usually when the weather decides to flip - either way knocks me into a flare). I keep waiting for 'the other shoe to drop' but so far, the combination is working for me...
