I’m so sorry you’re suffering. You mentioned a lot of supplements or taking high amounts of Vitamin D. I take several supplements which my Functional Medicine Doctor (chiropractor) prescribed for me and D-3 is one of them. I began my supplements about 2 years ago and they have made a huge difference in my strength on a daily basis. I also suffer from Hashimoto’s and Hypothyroidism which makes me tired some days. I’m praying that all we need is time. I will be into this 3 years in December, still without taste or smell, but other symptoms are better. I’ll take it as a win I guess…
