Day 5: Increased my dose of actifolate to half a tablet, no change. Day 6: Stayed on half a tablet of actifolate, took half a tablet of neurological health formula. Took my meds late in the morning and had my dinner at lunch time rather than in the evening today (I was planning to attend a meditation class). After dinner, started feeling much worse. Very tired and achy, headache. Kind of dizzy, feel slightly anxious. Couldn't go to work, lay down for a couple of hours instead. I think it could be the neurological health formula, but I'm not sure. I have ordered some FolaPro (L-5-Methyl Tetrahydrofolate) and some MegaFolinic (Folinic Acid) to take in place of the actifolate. I have also ordered some sublingual methylcobalamin to try in place of the hydoxocobalamin.
