Waynes, my husband has fibromyalgia, high cholesterol and some other health issues. I struggle with chronic neck and back pain, high cholesterol, high blood pressure, and chronic depression.
I started feeling better at about day 4 of my Whole30, and have been mostly pain free since then. I'm still on my meds for the pain but they used to just lessen the pain, make it bearable. Now, as long as I take my meds - I generally have NO PAIN at all. I can't believe it. My cholesterol and blood pressure are both in the normal range again as well! My chronic depression also got significantly better.
It took my husband 2-3 weeks to see any improvement, but he is now startingto feeling better. Still having bad flare days but not like it was before. There were days he couldn't get out of bed, and that's not happening now. I believe it may be a longer road for people with fibro, ME, or chronic fatigue types illnesses.
We just finished a whole30 about a week ago and were lazy with our reintroduction... So we are starting again. I have every confidence that we will both feel even better this time around.
Of course these are just our experiences, but I wanted to share it with you so you know that there are people here who understand and have some of the same struggles.
We can do it. You can do it. I wish you and your wife success!
