I doubt a CBC is sufficient since there are lots of things to test for. I’m far from an expert on this but my rough guess is the two most important are your magnesium level and potential vitamin B methylation problems, although again this is way out out my area of expertise. You could ask your doctor to test everything possible that might be contributing to your problem, then after he tells you the tests say “are you sure there isn’t anything extra you could add?”.
Your problem might be exasperated by a deficiency in some nutrient.
What would I ask for the next time I visit my GP to determine that? Would a CBC suffice, or would I need to ask for some more specific blood test?
