ENCORE: Q&A with Leyla, Part 2: Seasonal Affective Disorder

Do I have to replace minerals when using a reverse osmosis water purifier? Is anyone tracking whether vaccinated or unvaccinated people are getting long covid? What supplements should not be taken with low-dose aspirin?; Can you talk about chelation therapy and cardiovascular disease? I want to get the right lamp for Seasonal Affective Disorder.  What do you recommend?
