Hi, I am lost as to where to start with all this. I attached my knowyourgenetics.com basic report. I recently started taking a low dose of lithium orotate (1mg). Some notes: -My symptoms are anxiety, brain fog, fatigue, POTS, hypothyroidism, and low cortisol (by 24 hour salivary test). -My serum B12 level is slightly high. The upper range is about 900, and mine is just about 940. I don't take any B-Vitamins -I have eaten a paleo diet for a long time -Medications: Remeron, Zoloft, Baclofen, Depakote -Supplements: Magnesium, Ginger I should test for homocysteine, yeah? I guess I can start a low dose of 5MTHF, but should I try Methyl-B12 as well? What else? I'm wary to try new things, as I have been sensitive to things ever since developing the HPA dysregulation and POTS a year and a half ago. Thanks so much for any help!
